The visual system includes the eyes, the connecting pathways through to the visual cortex and other parts of the brain. The illustration shows the mammalian system.

The visual system is the part of the central nervous system which enables organisms to process visual detail, as well as enabling several non-image forming photoresponse functions. It interprets information from visible light to build a representation of the surrounding world. The visual system accomplishes a number of complex tasks, including the reception of light and the formation of monocular representations; the construction of a binocular perception from a pair of two dimensional projections; the identification and categorization of visual objects; assessing distances to and between objects; and guiding body movements in relation to visual objects. The psychological manifestation of visual information is known as visual perception, a lack of which is called blindness. Non-image forming visual functions, independent of visual perception, include the pupillary light reflex (PLR) and circadian photoentrainment.

Introduction[link]

The human eye
The image projected onto the retina is inverted due to the optics of the eye.

This article mostly describes the visual system of mammals, although other "higher" animals have similar visual systems. In this case, the visual system consists of:

• The eye, especially the retina
• The optic nerve
• The optic chiasma
• The optic tract
• The lateral geniculate body
• The optic radiation
• The visual cortex
• The visual association cortex.

Different species are able to see different parts of the light spectrum; for example, bees can see into the ultraviolet,^[1] while pit vipers can accurately target prey with their pit organs, which are sensitive to infrared radiation.^[2]

History[link]

In the second half of the 19th century, many motifs of the nervous system were identified such as the neuron doctrine and brain localisation, which related to the neuron being the basic unit of the nervous system and functional localisation in the brain, respectively. These would become tenets of the fledgling neuroscience and would support further understanding of the visual system.

The notion that the cerebral cortex is divided into functionally distinct cortices now known to be responsible for capacities such as touch (somatosensory cortex), movement (motor cortex), and vision (visual cortex), was first proposed by Franz Joseph Gall in 1810.^[3] Evidence for functionally distinct areas of the brain (and, specifically, of the cerebral cortex) mounted throughout the 19th century with discoveries by Paul Broca of the language center (1861), and Gustav Fritsch and Edouard Hitzig of the motor cortex (1871).^[3][4] Based on selective damage to parts of the brain and the functional effects this would produce (lesion studies), David Ferrier proposed that visual function was localised to the parietal lobe of the brain in 1876.^[4] In 1881, Hermann Munk more accurately located vision in the occipital lobe, where the primary visual cortex is now known to be.^[4]

Biology of the visual system[link]

Eye[link]

The eye is a complex biological device. The functioning of a camera is often compared with the workings of the eye, mostly since both focus light from external objects in the field of view onto a light-sensitive medium. In the case of the camera, this medium is film or an electronic sensor; in the case of the eye, it is an array of visual receptors. With this simple geometrical similarity, based on the laws of optics, the eye functions as a transducer, as does a CCD camera.

Light entering the eye is refracted as it passes through the cornea. It then passes through the pupil (controlled by the iris) and is further refracted by the lens. The cornea and lens act together as a compound lens to project an inverted image onto the retina.

Retina[link]

S. Ramón y Cajal, Structure of the Mammalian Retina, 1900

The retina consists of a large number of photoreceptor cells which contain particular protein molecules called opsins. In humans, two types of opsins are involved in conscious vision: rod opsins and cone opsins. (A third type, melanopsin in some of the retinal ganglion cells (RGC), part of the body clock mechanism, is probably not involved in conscious vision, as these RGC do not project to the lateral geniculate nucleus (LGN) but to the pretectal olivary nucleus (PON).^[5]) An opsin absorbs a photon (a particle of light) and transmits a signal to the cell through a signal transduction pathway, resulting in hyperpolarization of the photoreceptor. (For more information, see Photoreceptor cell).

Rods and cones differ in function. Rods are found primarily in the periphery of the retina and are used to see at low levels of light. Cones are found primarily in the center (or fovea) of the retina.^{[citation needed]} There are three types of cones that differ in the wavelengths of light they absorb; they are usually called short or blue, middle or green, and long or red. Cones are used primarily to distinguish color and other features of the visual world at normal levels of light.^{[citation needed]}

In the retina, the photoreceptors synapse directly onto bipolar cells, which in turn synapse onto ganglion cells of the outermost layer, which will then conduct action potentials to the brain. A significant amount of visual processing arises from the patterns of communication between neurons in the retina. About 130 million photoreceptors absorb light, yet roughly 1.2 million axons of ganglion cells transmit information from the retina to the brain. The processing in the retina includes the formation of center-surround receptive fields of bipolar and ganglion cells in the retina, as well as convergence and divergence from photoreceptor to bipolar cell. In addition, other neurons in the retina, particularly horizontal and amacrine cells, transmit information laterally (from a neuron in one layer to an adjacent neuron in the same layer), resulting in more complex receptive fields that can be either indifferent to color and sensitive to motion or sensitive to color and indifferent to motion.^{[citation needed]} Mechanism of generating visual signals: The retina adapts to its change in light through the use of the rods. In the dark, the retinal has a bent shape called cis-retinal. When light is present, the retinal changes to a straight form called trans-retinal and breaks away from the opsin. This is called bleaching because the purified rhodopsin changes from violet to colorless in the light. In the dark, the rhodopsin absorbs no light therefore releasing glutamate cells which inhibit the bipolar cell. This inhibits the release of neurotransmitters to the ganglion cell. In the light, glutamate secretion ceases which no longer inhibits the bipolar cell from releasing neurotransmitters to the ganglion cell and therefore an image can be detected.^[6][7]

The final result of all this processing is five different populations of ganglion cells that send visual (image-forming and non-image-forming) information to the brain:

1. M cells, with large center-surround receptive fields that are sensitive to depth, indifferent to color, and rapidly adapt to a stimulus;
2. P cells, with smaller center-surround receptive fields that are sensitive to color and shape;
3. K cells, with very large center-only receptive fields that are sensitive to color and indifferent to shape or depth;
4. another population that is intrinsically photosensitive; and
5. a final population that is used for eye movements.^{[citation needed]}

A 2006 University of Pennsylvania study calculated the approximate bandwidth of human retinas to be about 8960 kilobits per second, whereas guinea pig retinas transfer at about 875 kilobits.^[8]

In 2007 Zaidi and co-researchers on both sides of the Atlantic studying patients without rods and cones, discovered that the novel photoreceptive ganglion cell in humans also has a role in conscious and unconscious visual perception.^[9][10][11] The peak spectral sensitivity was 481 nm. This shows that there are two pathways for sight in the retina – one based on classic photoreceptors (rods and cones) and the other, newly discovered, based on photoreceptive ganglion cells which act as rudimentary visual brightness detectors.

Photochemistry[link]

In the visual system, retinal, technically called retinene₁ or "retinaldehyde", is a light-sensitive retinene molecule found in the rods and cones of the retina. Retinal is the fundamental structure involved in the transduction of light into visual signals, i.e. nerve impulses in the ocular system of the central nervous system. In the presence of light, the retinal molecule changes configuration and as a result a nerve impulse is generated.^{[citation needed]}

Fibers to thalamus[link]

Optic nerve[link]

Information flow from the eyes (top), crossing at the optic chiasma, joining left and right eye information in the optic tract, and layering left and right visual stimuli in the lateral geniculate nucleus. V1 in red at bottom of image. (1543 image from Andreas Vesalius' Fabrica)

The information about the image via the eye is transmitted to the brain along the optic nerve. Different populations of ganglion cells in the retina send information to the brain through the optic nerve. About 90% of the axons in the optic nerve go to the lateral geniculate nucleus in the thalamus. These axons originate from the M, P, and K ganglion cells in the retina, see above. This parallel processing is important for reconstructing the visual world; each type of information will go through a different route to perception. Another population sends information to the superior colliculus in the midbrain, which assists in controlling eye movements (saccades)^[12] as well as other motor responses.

A final population of photosensitive ganglion cells, containing melanopsin, sends information via the retinohypothalamic tract (RHT) to the pretectum (pupillary reflex), to several structures involved in the control of circadian rhythms and sleep such as the suprachiasmatic nucleus (SCN, the biological clock), and to the ventrolateral preoptic nucleus (VLPO, a region involved in sleep regulation).^[13] A recently discovered role for photoreceptive ganglion cells is that they mediate conscious and unconscious vision – acting as rudimentary visual brightness detectors as shown in rodless coneless eyes.^[9]

Optic chiasm[link]

The optic nerves from both eyes meet and cross at the optic chiasm,^[14][15] at the base of the hypothalamus of the brain. At this point the information coming from both eyes is combined and then splits according to the visual field. The corresponding halves of the field of view (right and left) are sent to the left and right halves of the brain, respectively, to be processed. That is, the right side of primary visual cortex deals with the left half of the field of view from both eyes, and similarly for the left brain.^[12] A small region in the center of the field of view is processed redundantly by both halves of the brain.

Optic tract[link]

Information from the right visual field (now on the left side of the brain) travels in the left optic tract. Information from the left visual field travels in the right optic tract. Each optic tract terminates in the lateral geniculate nucleus (LGN) in the thalamus.

Six layers in the LGN

Lateral geniculate nucleus[link]

The lateral geniculate nucleus (LGN) is a sensory relay nucleus in the thalamus of the brain. The LGN consists of six layers in humans and other primates starting from catarhinians, including cercopithecidae and apes. Layers 1, 4, and 6 correspond to information from the contralateral (crossed) fibers of the nasal retina (temporal visual field); layers 2, 3, and 5 correspond to information from the ipsilateral (uncrossed) fibers of the temporal retina (nasal visual field). Layer one (1) contains M cells which correspond to the M (magnocellular) cells of the optic nerve of the opposite eye and are concerned with depth or motion. Layers four and six (4 & 6) of the LGN also connect to the opposite eye, but to the P cells (color and edges) of the optic nerve. By contrast, layers two, three and five (2, 3, & 5) of the LGN connect to the M cells and P (parvocellular) cells of the optic nerve for the same side of the brain as its respective LGN. Spread out, the six layers of the LGN are the area of a credit card and about three times its thickness. The LGN is rolled up into two ellipsoids about the size and shape of two small birds' eggs. In between the six layers are smaller cells that receive information from the K cells (color) in the retina. The neurons of the LGN then relay the visual image to the primary visual cortex (V1) which is located at the back of the brain (caudal end) in the occipital lobe in and close to the calcarine sulcus. The LGN is not just a simple relay station but it is also a center for processing; it receives reciprocal input from the cortical and subcortical layers and reciprocal innervation from the visual cortex.^{[citation needed]}

Gray's FIG. 722– Scheme showing central connections of the optic nerves and optic tracts.

Optic radiation[link]

The optic radiations, one on each side of the brain, carry information from the thalamic lateral geniculate nucleus to layer 4 of the visual cortex. The P layer neurons of the LGN relay to V1 layer 4C β. The M layer neurons relay to V1 layer 4C α. The K layer neurons in the LGN relay to large neurons called blobs in layers 2 and 3 of V1.^{[citation needed]}

There is a direct correspondence from an angular position in the field of view of the eye, all the way through the optic tract to a nerve position in V1. At this juncture in V1, the image path ceases to be straightforward; there is more cross-connection within the visual cortex.

Visual cortex[link]

Visual cortex: V1, V2, V3, V4, V5 (also called MT)

The visual cortex is the largest system in the human brain and is responsible for processing the visual image. It lies at the rear of the brain (highlighted in the image), above the cerebellum. The region that receives information directly from the LGN is called the primary visual cortex, (also called V1 and striate cortex). Visual information then flows through a cortical hierarchy. These areas include V2, V3, V4 and area V5/MT (the exact connectivity depends on the species of the animal). These secondary visual areas (collectively termed the extrastriate visual cortex) process a wide variety of visual primitives. Neurons in V1 and V2 respond selectively to bars of specific orientations, or combinations of bars. These are believed to support edge and corner detection. Similarly, basic information about color and motion is processed here.^[16]

Visual association cortex[link]

As visual information passes forward through the visual hierarchy, the complexity of the neural representations increases. Whereas a V1 neuron may respond selectively to a line segment of a particular orientation in a particular retinotopic location, neurons in the lateral occipital complex respond selectively to complete object (e.g., a figure drawing), and neurons in visual association cortex may respond selectively to human faces, or to a particular object.

Along with this increasing complexity of neural representation may come a level of specialization of processing into two distinct pathways: the dorsal stream and the ventral stream (the Two Streams hypothesis,^[17] first proposed by Ungerleider and Mishkin in 1982). The dorsal stream, commonly referred to as the "where" stream, is involved in spatial attention (covert and overt), and communicates with regions that control eye movements and hand movements. More recently, this area has been called the "how" stream to emphasize its role in guiding behaviors to spatial locations. The ventral stream, commonly referred as the "what" stream, is involved in the recognition, identification and categorization of visual stimuli.

However, there is still much debate about the degree of specialization within these two pathways, since they are in fact heavily interconnected.^[18]

Visual System and Balance[link]

Along with proprioception and vestibular function, the visual system plays an important role in the ability of an individual to control balance and maintain an upright posture. When these three conditions are isolated and balance is tested, it has been found that vision is the most significant contributor to balance, playing a bigger role than either of the two other intrinsic mechanisms. ^[19] The clarity with which an individual can see his environment, as well as the size of the visual field, the susceptibility of the individual to light and glare, and poor depth perception play important roles in providing a feedback loop to the brain on the bodys movement through the environment. Anything that affects any of these variables can have a negative effect on balance and mainting posture. ^[20]. This effect has been seen in research involving elderly subjects when compared to young controls ^[21], in glaucoma patients compared to age matched controls^[22], cataract patients pre and post surgery ^[23], and even something as simple as wearing safety goggles ^[24]. Monocular vision (one eyed vision) has also been shown to negatively impact balance, which was seen in the previously referenced cataract and glaucoma studies^[25][26], as well as in healthy children and adults. ^[27]

William Leonard Roberts II (born January 28, 1976), better known by his stage name Rick Ross (often stylized as RICK RO$$), is an American rapper. He derived his stage name from the drug trafficker "Freeway" Ricky Ross, to whom he has no connection. Ross founded the record label Maybach Music Group, on which he released his studio albums Deeper Than Rap and Teflon Don, Ross was also the first artist signed to Diddy's management company Ciroc Entertainment. In early 2012, MTV named Ross as the Hottest MC In The Game.^[3]

Early life[link]

William Leonard Roberts II was born in Coahoma County, Mississippi.^[1] and raised in Carol City, Florida, near Miami.^[2] After graduating from Carol City Senior High School, he later attended the historically black college Albany State University on a football scholarship.^[4]

Music career[link]

After being signed to Suave House Records, former label for rap duo 8Ball & MJG, he eventually signed a deal with Slip-n-Slide Records, which has been under the Def Jam umbrella since 2006. While signed to Slip-n-Slide, Ross toured with fellow rapper Trick Daddy and made guest performances on other Slip-n-Slide albums.^[2]

[edit] Port of Miami (2006)

His debut album Port of Miami was released in August 2006 and debuted at the top spot on the Billboard 200 album chart, with sales at 187,000 units after its first week.^[5][6] Christian Hoard of Rolling Stone magazine predicted that it would be "the summer's biggest rap record".^[7] The second single was "Push It", which samples "Scarface (Push It to the Limit)", the theme song off the gangster film Scarface.^[8] The music video for "Push It" was modeled after the film.^[9] During that time, Ross made guest performances on two singles from DJ Khaled's debut Listennn... the Album: "Born-N-Raised" and "Holla at Me". Port of Miami received Gold certification from the Recording Industry Association of America on November 8, 2006.

[edit] Trilla (2008)

In March 2008, his second album Trilla was released and, as its predecessor Port of Miami had, debuted at the top of the Billboard 200.^[10] Its lead single "Speedin'" featuring R. Kelly peaked at #121 on the Billboard Hot 100; the next one, "The Boss" featuring T-Pain peaked at #17 on the Hot 100. The third single "Here I Am" featured Nelly and Avery Storm.^[11] MTV News ranked Ross on the fourth spot in its 2008 "Hottest MCs In The Game" list among ten rappers.^[12] The fourth single "This Is The Life" featured Trey Songz and was released in July.

[edit] Deeper Than Rap (2009)

"I look at the game and the business and all different aspects, it's a lot of great lyricists on the corner that will never properly understand the business and know how to market themselves and get in a position where they can gain capital. I look at all the strategies people use and what made them successful. What made Birdman just as relevant today after selling 50 million records? That intrigues me. To see the class of Jay-Z, his accomplishments and see how he sits backs and accurately makes his moves."^[13]

A track from the album called "Valley of Death" was what stood out to MTV reporters. In the song, Ross speaks briefly on his controversial stint as a prison guard. "Keep it trilla, nigga, never had a gun and badge," which he stresses, leaving the word that he was indeed an officer of the law. "Kept a nice watch, smoking on a hundred sack/ Back in the day I sold crack for some nice kicks/ Skippin' school, I saw my friend stabbed with an ice pick/ Can't criticize niggas trying to get jobs/ Better get smart, young brother, live yours." Later, he implies that while he was working as a corrections officer, he was on the streets. "Only lived once and I got two kids/ And for me to feed them, I'll get two gigs," he raps. "I'll shovel shit, I'll C.O./ So we can bow our heads and pray over the meatloaf." Although, he still provided no explanation for lying about being a C.O. to begin with, nor did he explain why he failed to pay child support for his children.^[14][15]

The cover of the May 2009 issue of XXL magazine, titled "Rick Ross Up in Smoke", featured Ross wearing a pair of Louis Vuitton sunglasses. After publication, a spokesperson for the luxury-goods maker contacted XXL to inform them that Ross was sporting fake sunglasses in the cover image.^[16] It was later revealed that the rapper was wearing authentic Louis Vuitton sunglasses which were altered by Jacob Bernstein, known as "The Sunglass Pimp". Bernstein defended his customizations despite Louis Vuitton's insistence that such modification and resale of trademarked property is not legal.^[17]

[edit] Teflon Don and other works (2010)

Rick Ross released his fourth studio album entitled Teflon Don, which was released on July 6, 2010. The lead is "Super High" featuring Ne-Yo. Actress Stacey Dash made an appearance in the music video. A second official single was released titled "Live Fast, Die Young" which features and is produced by Kanye West. The album debuted at #2 on the Billboard 200 selling 176,000 copies in its first week.

In November 2010, rapper and frequent collabourator, Diddy, who in 2009 signed Ross to a management deal with his Ciroc Entertainment, announced from his YouTube account, that him and Ross are working on an EP together, which is going to be released in 2011.^{[dated info]} A single has been released for the project, called "Another One".^[18]

[edit] God Forgives, I Don't (2011 - present)

Rick Ross had also announced the release of his next album, "God Forgives, I Don't", for December 13, 2011, however it was confirmed on November 17, 2011 it has been pushed back for release in 2012.^[19][20]

Rick Ross premiered two songs from his new album "God Forgives, I Don't", titled "You The Boss" and "I Love My Bitches".^[21]

Along with his music projects, Rick Ross was nominated by The Source as its "Man of the Year".^[22]

Rick Ross performed at BET Awards 2011, which aired on June 26, 2011.^[23] He also received a nomination for Best Male Hip Hop Artist.^[24] In early 2012, Ross was named the Hottest MC In The Game.^[3]

Personal life[link]

Correctional officer photos[link]

In July 2008, The Smoking Gun produced details linking Ross' social security number to an eighteen month stint as a correctional officer at the South Florida Reception Center, along with a photograph purporting to be Ross in his correctional officer uniform.^[25] Ross initially denied that the photograph was of him;^[26] after overwhelming evidence of his past came into the public's eye, Ross later admitted that he did work as a correctional officer in Florida during the early 1990s.^[27] In a 2008 interview with AllHipHop.com,^[28] "Freeway" Ricky Ross, claimed offense that Roberts used his name and identity when he learned that The Smoking Gun posted documents revealing Roberts' previous employment as a Florida correctional officer.^[29]

Legal issues[link]

Mugshot of Rick Ross taken in 2008.

In January 2008, Ross was arrested on gun and marijuana charges. During a deposition of Officer Rey Hernandez, a Miami Beach cop who arrested Ross, Ross's lawyer, Allan Zamren, asked Hernandez why Ross’s case was assigned to the gang task force. The officer stated that it was because Ross claimed affiliation with Carol City Cartel and other known gang members. Zamren then pressed Hernandez for a personal link between Ross and the gang members, but ultimately one could not be established.^[30]

In August 2008, YouTube entertainer DJ Vlad filed a lawsuit against Ross for assault and battery. Vlad claimed Ross organized an ambush on him at the 2008 Ozone Awards in Houston, Texas for asking questions about his past as a correctional officer.^[31]

On June 18, 2010, Freeway Ricky Ross sued Rick Ross for using his name,^[32] filing a copyright infringement lawsuit in a California Federal Court.^[32] Jay-Z had been called to testify in the lawsuit, as he was CEO of Def Jam when Ross/Roberts was signed.^[32] The reformed drug kingpin was looking for 10 million dollars in the lawsuit.^[32] Also, the release of his album, Teflon Don, was threatened to be blocked by Freeway Ricky Ross. A week after the filing of the lawsuit, Rick Ross responded to the charges: "It’s like owning a restaurant, you’re gonna have a few slip and falls. You get lawsuits, you deal with them, and get them out your way…sometimes you lose."^[33] He then denied rumors that he would change his name to "Ricky Rozay" as a consequence of the lawsuit. The lawsuit was thrown out of court on July 3, 2010^[34] and his album, Teflon Don, was released on July 20 as scheduled.

On March 26, 2011, Ross was arrested in Shreveport for possession of marijuana. According to the police records, a strong odor of marijuana was detected from his room at the Hilton in Downtown Shreveport.^[35]

Religion[link]

Rick Ross is a Christian,^[36] and in an interview with Corey "Coco Brother" Condrey on Lift Every Voice, he indicated that "I had told myself at one point no matter what I go through, I never question God."^[37] In addition, Ross indicated that he prays every time he goes on stage to perform.^[38]

Seizures[link]

On October 14, 2011 Rick Ross suffered two seizures in the same day, once in the morning and once again early evening. Following the morning seizure, he was unconscious and CPR was being performed. He did, however, post a video to his Twitter account later in the day saying that he was OK.^{[citation needed]} Ross boarded another plane later in the day and suffered another seizure. On October 14, the University of Alabama at Birmingham Hospital confirmed that Ross had been admitted to the emergency room. TMZ, who first reported the seizure, updated their story originally posted at 4:45 PST, stating that Ross was in stable condition.^{[citation needed]}

Feud with 50 Cent[link]

In January 2009, Ross started a feud with rapper 50 Cent because he supposedly looked at him the wrong way at the BET Awards. 50 Cent told news sources that he did not remember seeing Ross there.^[39] In late January, "Mafia Music", by Ross, leaked onto the Internet. There were several lines that seemed to diss 50 Cent. Days later, 50 Cent released "Officer Ricky (Go Head, Try Me)" in response to Ross's disparaging remarks on his "Mafia Music" song.

Before going to Venezuela, 50 Cent uploaded a video entitled "Warning Shot," wherein he stated: "Rick Ross- I'mma fuck your life up for fun." In addition, 50 Cent released the first of a series of "Officer Ricky" cartoons. Early in February, 50 Cent once again made a video which he uploaded to YouTube in which he interviewed "Tia", the mother of one of Ross's children. She verifies that he was a correctional officer and claims his whole persona is fake and fraudulent.^[40] On Thursday, February 5, 2009, Game, who 50 Cent has a long-standing "beef" with, called up Seattle R&B station KUBE. When asked about the beef between 50 Cent and Ross, Game sided with 50 Cent and said that things are not looking good for Ross. He offered to help, stating, "Rick Ross, holla at your boy, man," and, "50 eating you, boy."^[41] On his album Deeper Than Rap, Ross references 50 Cent in the song "In Cold Blood". A video for the song was released that portrayed 50 Cent's mock funeral. Upon release, Ross stated that he has ended 50 Cent's career.^[42] That same day Ross released a new diss track called "Push 'Em Over The Edge". The next day 50 Cent released the controversial video "A Psychic Told Me", dissing DJ Khaled. On February 12, 50 Cent responded with "Tia Told Me", along with Lloyd Banks' response "Officer Down" and Tony Yayo's "Somebody Snitched".

In an interview, 50 Cent said Ross is "Albert From CB4. You ever seen the movie? He's Albert," he added. "It never gets worse than this. You get a guy that was a correctional officer come out and base his entire career on writing material from a drug dealer's perspective."^[43]
