The cerebellum (Latin for "little brain") is a region of the brain that plays an important role in motor control. It may also be involved in some cognitive functions such as attention and language, and in regulating fear and pleasure responses, but its movement-related functions are the most solidly established. The cerebellum does not initiate movement, but it contributes to coordination, precision, and accurate timing. It receives input from sensory systems of the spinal cord and from other parts of the brain, and integrates these inputs to fine-tune motor activity. Cerebellar damage produces disorders in fine movement, equilibrium, posture, and motor learning.
Anatomically, the cerebellum has the appearance of a separate structure attached to the bottom of the brain, tucked underneath the cerebral hemispheres. Its cortical surface is covered with finely spaced parallel grooves, in striking contrast to the broad irregular convolutions of the cerebral cortex. These parallel grooves conceal the fact that the cerebellar cortex is actually a continuous thin layer of tissue tightly folded in the style of an accordion. Within this thin layer are several types of neurons with a highly regular arrangement, the most important being Purkinje cells and granule cells. This complex neural organization gives rise to a massive signal-processing capability, but almost all of its output passes through a set of small deep cerebellar nuclei lying in the interior of the cerebellum.
The Cerebellum is a quarterly peer-reviewed scientific journal founded in 2002. It is published by Springer Science+Business Media on behalf of the Society for the Research on the Cerebellum. It is devoted to research about the cerebellum and its roles in ataxia and other disorders.
The journal is abstracted and indexed in Academic Search, Chemical Abstracts Service EBSCO databases, BIOBASE, EMBASE, Neuroscience Citation Index, PsycINFO, PubMed/MEDLINE, Science Citation Index Expanded, Scopus, Summon by Serial Solutions, and VINITI. According to the Journal Citation Reports, the journal's 2009 impact factor is 3.280.
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.
The human brain is the main organ of the human central nervous system. It is located in the head, protected by the skull. It has the same general structure as the brains of other mammals, but with a more developed cerebral cortex. Large animals such as whales and elephants have larger brains in absolute terms, but when measured using a measure of relative brain size, which compensates for body size, the quotient for the human brain is almost twice as large as that of a bottlenose dolphin, and three times as large as that of a chimpanzee, though the quotient for a treeshrew brain is larger than that of a human's. Much of the size of the human brain comes from the cerebral cortex, especially the frontal lobes, which are associated with executive functions such as self-control, planning, reasoning, and abstract thought. The area of the cerebral cortex devoted to vision, the visual cortex, is also greatly enlarged in humans compared to other animals.
Stanford University School of Medicine is the medical school of Stanford University and is located in Stanford, California. It is the successor to the Medical Department of the University of the Pacific, founded in San Francisco in 1858 and later named Cooper Medical College; the medical school was acquired by Stanford in 1908. Due to this descent, it ranks as the oldest medical school in the Western United States. The medical school moved to the Stanford campus near Palo Alto, California in 1959.
The School of Medicine, along with Stanford Health Care and Lucile Packard Children's Hospital, is part of Stanford Medicine. It is a research-intensive institution that emphasizes medical innovation, novel methods, discoveries, and interventions in its integrated curriculum.
In 1855, Illinois physician Elias Samuel Cooper moved to San Francisco in the wake of the California Gold Rush. In cooperation with the University of the Pacific (also known as California Wesleyan College), Cooper established the Medical Department of the University of the Pacific, the first medical school on the West Coast, in 1858, on Mission Street near 3rd Street in San Francisco. The school underwent many changes until Cooper's nephew, Levi Cooper Lane, established a new campus at the intersection of Webster and Sacramento Streets in 1882; at that time, the school was christened Cooper Medical College. Lane also built a hospital and a nursing school (forerunner of the Stanford School of Nursing) and made provision for the creation of Lane Medical Library.

In my 2-Minute Neuroscience videos I explain neuroscience topics in 2 minutes or less. In this video, I discuss the cerebellum. I describe the location of the cerebellum in the nervous system and its role in facilitating movement. I cover the different regions of the cerebellum: the cerebrocerebellum, spinocerebellum, vermis, and vestibulocerebellum. Lastly, I discuss the cerebellar peduncles as the routes by which the cerebellum communicates with the rest of the nervous system and the deep cerebellar nuclei as the primary output cells of the cerebellum. TRANSCRIPT: Welcome to 2 minute neuroscience, where I simplistically explain neuroscience topics in 2 minutes or less. In this installment I will discuss the cerebellum.

An introduction to the cerebellum and an overview of the main models of cerebellar function.
Cerebellum Dissection Video 1 by Dr Sanjoy Sanyal, Professor and Course Director of Neuroscience and FCM-III Neurology in the Caribbean. This is a full view of the Cerebellum, Brainstem and posterior Cranial fossa. It demonstrates the Cerebellar Hemispheres, the fissures, the Anatomical lobes, the Functional divisions of the Cerebellum, the Vermis, the Cerebellar Peduncles and tracts running though them. ERRATA CORRIGENDUM: Because the running commentary is impromptu, there is the inevitable slip of the proverbial tongue!! At 7.01, the Cerebral Hemisphere (Neo / Cerebro / Ponto Cerebellum is inadvertently referred to as the phylogenetically 'oldest' part of the Cerebellum. It should read as 'newest' part of the Cerebellum. Inadvertent error is regretted. Camera person is Mr Mark Lessard, ...

The gross features of the cerebellum are shown. The three peduncles are demonstrated, noting their input and output to and from the cerebellum. Emphasis is given to symptoms of cerebellar disease appearing on the same side of the body. Special emphasis is given to cortical-cerebellar connections, stressing the need for the pathways to cross twice in order to work with the descending corticospinal tract. Cerebellar functions and dysfunctions are discussed while showing clinical examples of patients with cerebellar disease.
The cerebellum is a central nervous system organ located directly behind the brainstem. It occupies therewith the posterior cranial fossa below the cerebellar tentorium, The cerebellum is attached to the brainstem by three pairs of cerebellar peduncles. "The Superior, The Middle and the Inferior cerebellar peduncle" The cerebellum contributes primarily to balance and motor coordination. The concentric grooves that marks the surface of the cerebellum give it a multi-foliated appearance. The cerebellum is divided into three main lobes: anterior, posterior and flocculonodular lobe. These lobes are subdivided into ten lobules by secondary grooves. The cerebellum contains a central region "median" called: the cerebellar vermis, and three Deep cerebellar nuclei : dentate, interposed and fastigi...

The Human Brain series takes a look into each structure of the brain and describes how this amazing, complex organ works. Part 9 of the Human Brain series describes the cerebellum. The cerebellum monitors and regulates motor behavior, particularly automatic movements. Some recent studies have associated the cerebellum with cognitive functions, such as learning and attention. Although the cerebellum accounts for roughly 10% of total brain weight, it contains more neurons than the rest of the brain combined. The cerebellum is also one of the few mammalian brain structures where adult neurogenesis has been confirmed. Functions associated with the cerebellum include coordination of voluntary movement, motor-learning, balance, reflex memory, posture, timing, and sequence learning. Case Stu...
Heather and David Britton want everyone to understand a few things about their giggling, bespectacled 3-year-old son, Chase. "He's happy. We call him the Little Gremlin. He loves to play tricks on people. He loves to sing. His goal in life is to make people smile," Heather Britton told AOL News. "He's got so much love around him. We're an extremely happy family. His story is not tragic." But to an outsider, the Brittons' story might seem heartbreaking. Another son, Trey, was born 11 weeks early and only expected to live moments. Instead, he died six weeks after his birth in 2008, on the same day he was scheduled to receive a liver transplant. Cleared to get pregnant again, the couple was thrilled when Chase was conceived, Britton said. They were eager to give older son Alex, 13...
Tout semblait sourire à Zorro
Quand il décide de faire escroc
De basculer pour palper gros, repartir à zéro.
Lui qu'aimait pourtant pas les soucis, fût en cinq sec servi !
(c'est 5 sets mec !)
Il m'a dit :
"Je paie cher, de ma vie
C'est l'enfer qui me suit mais qui me tient debout aussi !
Je paie fort, de ma vie
C'est mon sort qui me suit, ma folie"
C'est enfin le sommet, la gloire
Le type se met alors à croire
Que rien n'arrêtera son réseau
Sauf si on le plante dans le dos !
Voilà pourquoi Zorro tomba de haut en bas
Il me dit en face, juste comme ça :
"Je paie cher, de ma vie
C'est l'enfer qui me suit mais qui me tient debout aussi !
Je paie fort, de ma vie
C'est mon sort qui me suit, ma folie"
Un bien mal acquis, ne profite jamais
Zorro en fait les frais et prends le maquis
Il prie, il se cache
Il attend que passe le vent.
Puis s'installe, se refait plus fort
Tout recommence, le biz, la transe
On ne change pas ! même si parfois...
On paie cher, de nos vies.
C'est l'enfer qui nous suit mais qui maintient debout aussi !
On paie fort, de nos vies
On reste les mêmes, c'est ainsi...
