The Cerebellum
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,[1] but its movement-related functions are the most solidly established. The cerebellum does not initiate movement, but contributes to coordination, prec...
متن کاملThe Cerebellum
THE CEREBELLUM (Latin, little brain) constitutes only 10% of the total volume of the brain but contains more than half of all its neurons. These neurons are arranged in a highly regular manner as repeating units, each of which is a basic circuit module. Despite its structural regularity the cerebellum is divided into several distinct regions, each of which receives projections from different po...
متن کاملThe cerebellum and cerebellum-like structures of cartilaginous fishes.
The cerebellum is well developed in cartilaginous fishes, with the same cell types (barring basket cells) and organizational features found in other vertebrate groups, including mammals. In particular, the lattice-like organization of cerebellar cortex (with a molecular layer of parallel fibers, interneurons, spiny Purkinje cell dendrites, and climbing fibers) is a defining characteristic. In a...
متن کاملCerebellum and nonmotor function.
Does the cerebellum influence nonmotor behavior? Recent anatomical studies demonstrate that the output of the cerebellum targets multiple nonmotor areas in the prefrontal and posterior parietal cortex, as well as the cortical motor areas. The projections to different cortical areas originate from distinct output channels within the cerebellar nuclei. The cerebral cortical area that is the main ...
متن کاملProcedural Learning: Cerebellum Models
Article Synopsis: (100 words) The cerebellum is a key structure for the control of movement. However, the exact role of the cerebellum in motor control is unclear or at least highly controversial. One prominent hypothesis is that the cerebellum is important for motor learning. We review the evidence used to support this hypothesis during procedural or skill learning and find that though it is c...
