Meissner's Corpuscle
This video depicts a rotating view of a Meissner's corpuscle in a 60 μm thick section of a human skin punch biopsy from the fingertip. Meissner's corpuscles are located in the dermal papillae beneath the epidermis and detect light touch. They are innervated by 1 or more myelinated nerve axons which become unmyelinated within the corpuscle, as well as by other unmyelinated axons. The axons are d

How the Body Works : The Sensory Cortex and Touch
The Sensory Cortex and Touch
The sensory cortex, as represented in red, behind the central groove of the brain, is the primary area for the interpretation of incoming sensory information. The association area coordinates this information. The sense of touch involves the stimulation of receptors in the skin. The most superficial receptors are found in the epidermis. They are the free nerve e

Here is a song I created to help my 6th grade students study. I hope you enjoy.
Skin is more than a typical kind of thing
Protects us against damage and from infection, oh oh
Removes waste, collects info
Two main layers-outer, inner, then subcutaneous
Epidermis is the outer, filled with keratin, oh oh
Dermis has the receptors
Dermis, blood cells, and then the other structures

What is a Pacinian Corpuscle?
Mechanoreceptors are specialized structures that provide information to the central nervous system about touch, pressure, vibration, and cutaneous tension. There are four main types of mechanorecptors located within the hand; Meissner’s corpuscles, Pacinian corpuscles, Merkel’s disks, and Ruffini’s corpuscles
Pacinian corpuscles make up 10–15% of the cutaneous receptors in the hand.
These structures are nerve endings in the skin responsible for sensitivity to vibration and pressure. They respond only to sudden disturbances and are especially sensitive to vibration. The vibrational role may be used to detect surface texture, e.g., rough vs. smooth. Pacinian corpuscles act as very rapidly adapting mechanoreceptors. Groups of corpuscles respond to pressure changes, e.g. on grasping or releasing an object.
The Pacinian corpuscle is oval-shaped and approximately 2 mm in length. The entire corpuscle is wrapped by a layer of connective tissue. It has 20 to 60 concentric lamellae composed of fibrous connective tissue and fibroblasts, separated by gelatinous material. The lamellae are very thin, flat, modified Schwann Cells. In the center of the corpuscle is the inner bulb, a fluid-filled cavity with a single afferent unmyelenated nerve ending.
Pacinian corpuscles are rapidly adapting receptors that detect gross pressure changes and vibrations in the skin. Deformation in the corpuscle causes the action potentials to be generated by opening pressure-sensitive sodium ion channels. These corpuscles are especially susceptible to vibrations, which they can sense even centimeters away. It is thought that they respond to high-velocity changes in joint position.
These structures were named after Filippo Pacini (1812-1883) who discovered them in 1831 during a dissection class.

This video depicts a rotating view of a Meissner's corpuscle in a 60 μm thick section of a human skin punch biopsy from the fingertip. Meissner's corpuscles are located in the dermal papillae beneath the epidermis and detect light touch. They are innervated by 1 or more myelinated nerve axons which become unmyelinated within the corpuscle, as well as by other unmyelinated axons. The axons are detected by immunofluorescence staining for the axonal marker, PGP9.5 (red). The myelin sheath around myelinated axons is visualized by co-staining for myelin basic protein, MBP (green). This confocal microscope video (see below) was produced in the research laboratory at Therapath, a neuropathology company specializing in nerve analysis.

The skin is a highly specialized sensory organ. It contains receptors for pain, pressure, cold and heat. The receptors detect stimuli and transmit them to the brain. The Meissner's corpuscle is sensitive to touch. It helps us to perceive the surface structure and dimensions of objects. This is particularly important with very small objects. Meissner's corpuscles react above all to pressure changes within the skin. They hardly respond to constant pressure.

In this USMLE Step neuroanatomy video I will be discussing the Posterior Column-Medial Lemniscus pathway starting from the sensors (Meissners, Pacinian, Spindle Fibers) to spinal cord, medulla oblongata, pons, midbrain, thalamus, internal capsule and the primary somatosensory cortex.
Dorsal column functions for proprioception, fine touch, 2 point discrimination and vibration sensation.
THe medulla oblangata is made up of pyramids and olives. From the medulla oblangata are two inferior cerebellar peduncles which go to the cerebellum. Above this is the pons and midbrain which do not play a very important role in the dorsal column-medial lemniscus pathway.
Above this is the Thalamus which is broken up into three parts, Anterior thalamus, Medial Thalamus and Ventral thalamus. The ventral thalamus is made up of Ventral anterior, Ventral Intermediate and Ventral Posterior which is split in Ventral posterior lateral and Ventral Posterior Medial.
The receptors involved in the dorsal column-medial lemsniscus pathway are the meissner's corpuscles, pacinian corpuscles and the spindle fibers and golgi tendon.
Initially it will go to the dorsal root ganglion and go into the gray matter of the spinal cord. Under T6 it will go into the Fasiculus Gracilis and moves up into the corresponding Fasciculus Gracilis. Once you go above the T6 vertebrae and new tract is added to the dorsal column called the fasciculus cuneatus which is added to both sides. Therefore there are four tracts now formed. The fasciculus cuneatus carries the infromation related to arms and upper trunk.
In the midbrain the name changes from fasciculus gracilis to nucleus gracilis and the name changes from fasciculus cuneatus to nucleus cuneatus. Therefore the dorsal column has name changes once in the midbrain. Here the second neurons are formed and this is the first time there is a synapse. Here two types of fibers are formed. The external arcuate fibers go into the inferior cerebellar peduncle and send information to the cerebellum about the proprioception. These fibers are ipsilateral which are important because the internal arcuate fibers will cross over in the medulla oblangata and form the medial lemniscus. Therefore it is no longer called the dorsal column.
In the pons the tracts move straight through and don't really do anything. Here the medial lemniscus does move lateraly a small amount as it goes up to the midbrain. Once in the midbrain it will go into the thalamus.
In the thalamus the medial lemniscus will go to the ventroposterior lateral aspect of the thalamus. Here the third degree neurons are formed and the neurons go to the posterior horn of the internal capsule. FInally it will expand as the corona radiata and go into the cerebrum in the post-central gyrus also known as the primary somatosensory cortex.
Hope you learned a lot from my neuroanatomy video looking at the Dorsal Column-Medial Lemniscus tract. Hope this prepares you well for the USMLE Step 1.

CONTAINS DISTURBING SOUNDS AND IMAGERY OF CHILD ABUSE
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
NHS performs genital mutilation:
"It is important to note however that some PCTs in England do currently fund religious or ritual circumcision on the NHS. Each PCT takes decisions based on priorities that relate to its own local population."
http://www.nhs.uk/Conditions/Circumcision/Pages/Introduction.aspx
To give you an idea of how many inflictions of male genital mutilation are happening in the UK, this was stated in: http://www.secularism.org.uk/news/2013/01/sheffield-hospitals-plan-to-charge-for-non-medical-circumcision
"Hospitals in Sheffield carry out about 200 non-medical male circumcisions a year, costing the Health Authority in the region of £170,000." Do the maths.

Circumcision statistics available for 2009 - NHS Heywood Middleton and Rochdale
http://www.hmr.nhs.uk/attachments/article/139/WEB-FOI-11-279.pdf
{Routine and ritual circumcisions carried out at NHS hospitals for patients registered with NHS Heywood Middleton and Rochdale = 63 }
What circumcision steals:
Foreskin -
The foreskin comprises roughly 50% (and sometimes more) of the mobile skin system of the penis. If unfolded and spread out flat, the average adult foreskin would measure about 15 square inches - the size of a three-by-five index card. This highly specialized tissue normally covers the glans and protects it from abrasion, drying and callusing (also called keratinization).
Frenar Band, or Ridged Band -
The frenar band is a group of soft ridges near the junction of the inner and outer foreskin. This region is the primary erogenous zone of the intact male body. Loss of this delicate belt of densely innervated, sexually responsive tissue reduces the fullness and intensity of sexual response.
Gliding Action -
The foreskin's gliding action is a hallmark feature of the normal, natural, intact penis. Without this gliding action, the corona of the circumcised penis can function as a one-way valve, making artificial lubricants necessary for comfortable intercourse.
Meissner's Corpuscles -
Circumcision removes the most important sensory component of the foreskin - thousands of coiled fine-touch receptors called Meissner's corpuscles. Also lost are branches of the dorsal nerve, and between 10,000 and 20,000 specialized erotogenic nerve endings of several types.
Frenulum -
The frenulum is a highly erogenous V-shaped structure on the underside of the glans that tethers the foreskin. During circumcision it is frequently either amputated with the foreskin or severed, which destroys or diminishes its sexual and physiological functions.
Dartos Fascia -
Circumcision removes approximately half of this temperature-sensitive smooth muscle sheath which lies between the outer layer of skin and the corpus cavernosa.
Size -
Circumcision removes some of the length and girth of the penis - its double-layered wrapping of loose and usually overhanging foreskin is removed. A circumcised penis is truncated and thinner than it would have been if left intact.

The Sensory Cortex and Touch
The sensory cortex, as represented in red, behind the central groove of the brain, is the primary area for the interpretation of incoming sensory information. The association area coordinates this information. The sense of touch involves the stimulation of receptors in the skin. The most superficial receptors are found in the epidermis. They are the free nerve endings, which respond to touch and pain; Merkel's disks, which respond to continuous touch; and the end bulbs of Krause, the receptors that probably register cold. Below the epidermis is the dermis. In the dermis are Meissner's corpuscles, which send information to the brain about the texture of the object that is being touched; nerve endings around the bases of the hair follicles, which are stimulated by movement of the hair; Pacinian corpuscles, which respond to pressure; and Ruffini corpuscles, which respond to changes in temperature.

Here is a song I created to help my 6th grade students study. I hope you enjoy.
Skin is more than a typical kind of thing
Protects us against damage and from infection, oh oh
Removes waste, collects info
Two main layers-outer, inner, then subcutaneous
Epidermis is the outer, filled with keratin, oh oh
Dermis has the receptors
Dermis, blood cells, and then the other structures
Touch receptors, Meissner's corpuscles
Sweat glands, hair muscles, hair plexuses
Pacinian corpuscles and pain receptors
Oh oh, brain interprets the impulse
The integumentary
Skin has different layers
Covers body will protect it
Largest organ in your body that's right
Come on, that's right
Nails will grow from a root

Come on, that's right, covers you
Here's the deal, touch and feel
Nails forming firm pads
To support fingertips, made of keratin, oh oh
Cuticle is the thick skin
Oh yeah
Hair grows out, of deep pits they're called follicles
At the base of each hair divide push hair up, oh oh
Cutting hair it will not hurt, no no

Melanin colors them darkness to light
Come on, that's right, covers you
Skin producing melanin, brown substance in you
Absorbing UV rays, Sun blocking hue
Epidermis holds the key color on the base
Fair skinned it is then, melanin colors skin
Dark kinda skin large amounts usually
Melanin goin' all through it, truthfully
Dark hair will have it, fair mixed with sulfur, melanin

"In the Epidermis" Lyrics
Skin
Integumentary
Is what, protects me
insulates me and
keeps organs in my body
And first, is hair shafts
they grow, from follicles
Arrector Pili Muscles
Pull the hair when youre cold
Tell me why
Doesnt matter if youre black or white
Tell me why
We all have melanocytes
Tell me why
They are in the epidermis
The topmost layer
Stratified squamous cells
Make up your epidermis
Yes I know, it's too late
Since the cells are dead anyway
Tell me why
Doesnt matter if youre black or white
Tell me why
We all have melanocytes
Tell me why
They are in the epidermis
The topmost layer
Now I can see that we've reached the dermis
Its composed of two layers, papillae and
Reticular layer
has so many things
Now well describe them to you
Papillary
Fingerprints and
Meissners Corpuscles (feel touch)
Feel pain, feel pain, feel pain, feel pain (by free nerves)
But thats not all!!!
Collagen and elastin
Are in the reticular layer
Pacinian Corpuscles
Feel pressure when youre pinched
Dont forget
Nerves help us feel the world
Arteries
Take the blood to the skin
And the veins
Take the blood to the heart
Still in the reticular
And our sweat
Comes from the sudoriferous
So you smell too
Sebaceous glands makes skin oily
Were at the
last layer of the skin
It is hypodermis
Made of those fat cells
(Adipose)

Many parents do not realize it, but believe it or not, there are serious risks to infant circumcision. It isn’t some simple harmless procedure, like most American doctors would have you believe. As a matter of fact, the reason an average of 120 baby boys die in AMERICA each & every year, are because of some of the risks involved. Lets list all these risks, shall we…
1. Hemorrhaging
2. Infection – Dangerous because infants have no immune system
3. Adhesions
4. Wound Not Healing correctly
5. Baby goes into Shock – From blood loss and/or immense amount of pain.
6. Botched Circumcision - Usually requires 2nd risky procedure to fix.
7. Loss of 20,000+ Nerves and Nerve Endings
8. Loss of 16 Biological Functions
9. Vomiting During Procedure – from the pain & distress they’re in. Many doctors will not allow infants to feed beforehand for this reason.
10. Baby Unwilling to Latch or Nurse Afterwards - Can harm breastfeeding
11. Post-Procedure Pain
12. Death – The worst risk of all! Nothing out weighs this risk! What is worth risking the death of your newborn baby?
All mammals, both male & female, are born with a form of foreskin! For human females, it's the labia & clitoral hood, with an average of 8,000 nerves. For human males, foreskin has 16 biological functions & 20,000+ nerves! It is dominantly America who practices Routine Infant Circumcision. Outside the United States, it's uncommon to cut up the genitals of a healthy newborn. There is no medical need for it. A little over 80% of the world's men are intact! He was born with foreskin for a reason. He was born the way he was meant to be. I'll list all the 16 functions his foreskin has...
1. Erotic pleasure, especially via the ridged band and Meissner's corpuscles.
2. Acts as a rolling bearing in intercourse and masturbation. Meaning no lotion or lube needed!
3. Prevents dyspareunia (painful intercourse)
4. Stimulates partner's genitalia, giving erotic pleasure.
5. Supplies skin to cover the shaft during erection & prevent tightness.
6. Stores pheromones and releases them on arousal!
7. Stores, releases and helps distribute natural lubricants!
8. Makes the glans (head of the penis) a visual signal of sexual arousal.
9. Provides a seal against the vaginal wall to contain semen. Which is nature's way of increasing chances of pregnancy. It also helps lock in female wetness, meaning the woman doesn't have issues staying wet!
10. Prevents the glans becoming Keratinised, and keeps it soft n moist. Think of it like an eyelid that keeps your eyeballs soft n moist.
11. Protects the thin-skinned glans against injury.
12. Protects the nerves of the glans, retaining their erotic function.
13. In infancy, protects the urethra against contamination & meatal stenosis. How? It's sealed closed around the glans, only allowing room for urination to come out. As the boy grows older & closer to puberty, it will gradually detach & become retractable on it's own.
14. Provides lysosomes for bacteriostatic action around the glans. You know how women have a balance of good n bad bacteria? So do men. It's natural. If it was nasty or dangerous, men would be disgusted by women & refuse to have sex.
15. Pigmented, it protects the unpigmented glans against sunburn.
16. Vascular (rich in blood vessels that bring heat to the tissues), it protects the less vascular glans against frostbite.
If we're smart enough to protect our baby girls, we should be smart enough to protect our baby boys as well! Equal rights for both!

The cerebral cortex is the outermost layered structure of neural tissue of the cerebrum (brain), in humans and other mammals. It covers the cerebrum, and is divided into two cortices, along the sagittal plane, covering the left and right cerebral hemispheres. The medial longitudinal fissure is a deep groove that separates these two hemispheres. The cerebral cortex plays a key role in memory, attention, perceptual awareness, thought, language, and consciousness. The neocortex which is the major part of the cortex, consists of up to six horizontal layers, each with a different composition in terms of neurons and connectivity. The human cerebral cortex is 2 to 4 millimetres (0.079 to 0.157 in) thick.
It is referred to as gray matter as it consists of cell bodies and capillaries and contrasts with the underlying white matter, that consists mainly of the white myelinated sheaths of neuronal axons.

Bio:
John M. Martinis attended the University of California at Berkeley from 1976 to 1987, where he received two degrees in Physics: B.S. (1980) and Ph.D. (1987). His thesis research focused on macroscopic quantum tunneling in Josephson Junctions. After completing a post-doctoral position at the Commisiariat Energie Atomic in Saclay, France, he joined the Electromagnetic Technology division at NIST in Boulder. At NIST he was involved in understanding the basic physics of the Coulomb Blockade, and worked to use this phenomenon to make a new fundamental electrical standard based on counting electrons. While at NIST he also invented microcalorimeters based on superconducting sensors for x-ray microanalysis and astrophysics. In June of 2004 he moved to the University of California, Santa Barbara where he currently holds the Worster Chair. At UCSB, he has continued work on quantum computation. Along with Andrew Cleland, he was awarded in 2010 the AAAS science breakthrough of the year for work showing quantum behavior of a mechanical oscillator.
Abstract:
Superconducting quantum computing is now at an important crossroad, where "proof of concept" experiments involving small numbers of qubits can be transitioned to more challenging and systematic approaches that could actually lead to building a quantum computer. Our optimism is based on two recent developments: a new hardware architecture for error detection based on "surface codes" [1], and recent improvements in the coherence of superconducting qubits [2]. I will explain how the surface code is a major advance for quantum computing, as it allows one to use qubits with realistic fidelities, and has a connection architecture that is compatible with integrated circuit technology. Additionally, the surface code allows quantum error detection to be understood using simple principles. I will also discuss how the hardware characteristics of superconducting qubits map into this architecture, and review recent results that suggest gate errors can be reduced to below that needed for the error detection threshold.
