corpus callosum
The cortex is divided into two sections referred to as the cerebral cortex and the cerebellar cortex.
purkinje cells
Grey matter is distributed at the surface of the cerebral hemispheres (cerebral cortex) and of the cerebellum (cerebellar cortex), as well as in the depths of the cerebrum (thalamus; hypothalamus; subthalamus, basal ganglia - putamen, globus pallidus, nucleus accumbens; septal nuclei), cerebellar (deep cerebellar nuclei - dentate nucleus, globose nucleus, emboliform nucleus, fastigial nucleus), brainstem (substantia nigra, red nucleus, olivary nuclei, cranial nerve nuclei) and spinal grey matter (anterior horn, lateral horn, posterior horn).
Cerebral hemispheres (left and right)
Granule cells are the only excitatory neurons in the cerebellar cortex. They receive input from mossy fibers and synapse onto Purkinje cells and Golgi cells.
No. Huntington's Disease is a pathological process affecting subcortical structures, not the cerebellar cortex. It does cause generalized atrophy of the cerebral cortex, over time, however. It is a genetic disorder, autosomal dominant in its transmission process, and occurring on chromosome number 4.
The cerebral cortex is composed of two hemispheres: the left hemisphere and the right hemisphere. Each hemisphere controls the opposite side of the body and is responsible for different functions. The two hemispheres communicate with each other through a structure called the corpus callosum.
cerebral hemispheres
The cerebellar cortex consists mainly of gray matter, which is responsible for processing and integrating sensory information as well as coordinating motor movements.
Damage to the cerebellar pathways can result in tremors and jerky movements. Specifically, damage to the spinocerebellar pathway or cerebellar cortex can lead to uncoordinated and irregular movements. These movements are often seen in conditions such as cerebellar ataxia.
You actually have two as the brain is divided into two hemispheres each covered by a cortex and connected by nerve fibers in the corpus callosum.
