Cerebellar in a sentence

A climbing fiber gives off collaterals to the deep cerebellar nuclei before entering the cerebellar cortex, where it splits into about 10 terminal branches, each of which gives input to a single Purkinje cell.

Clinical significance main Altered walking gait of a woman with cerebellar disease The most salient symptoms of cerebellar dysfunction are motor-related—the specific symptoms depend on which part of the cerebellum is involved and how it is disrupted.

Experiments showed that lesions localized either to a specific part of the interposed nucleus (one of the deep cerebellar nuclei) or to a few specific points in the cerebellar cortex would abolish learning of a conditionally timed blink response.

Animals and humans with cerebellar dysfunction show, above all, problems with motor control, on the same side of the body as the damaged part of the cerebellum.

As cerebellar ataxia becomes severe, great assistance and effort are needed to stand and walk.

Cerebellar ataxia could result with incoordination of movement, particularly in the extremities.

Cerebellar damage can also produce a “wing-beating” type of tremor called rubral or Holmes’ tremor — a combination of rest, action, and postural tremors.

Cerebellar tremor is caused by lesions in or damage to the cerebellum resulting from stroke, tumor, or disease such as multiple sclerosis or some inherited degenerative disorder.

However, the cerebellar theory is not supported by controlled research studies. citation Genetics main Research into potential genetic causes of dyslexia has its roots in post- autopsy examination of the brains of people with dyslexia.

In classic cerebellar tremor, a lesion on one side of the brain produces a tremor in that same side of the body that worsens with directed movement.

Inferior cerebellar peduncle integrates proprioceptive info and outputs to the vestibulocerebellum.

Injuries to the brain and spinal cord, including cortex, subcortex, cerebellar, and even the neural pathway regions.

Instead, the primary targets of Purkinje cells are a distinct type of cell distributed across the cerebellar cortex, a type not seen in mammals.

It sends fibers to deep cerebellar nuclei that, in turn, project to both the cerebral cortex and the brain stem, thus providing modulation of descending motor systems.

Most subsequent cerebellar-learning models, however, have followed Albus in assuming that climbing fiber activity would be an error signal, and would cause synchronously activated parallel fiber inputs to be weakened.

Some of these later models, such as the Adaptive Filter model of Fujita citation made attempts to understand cerebellar function in terms of optimal control theory.

Some parts, such as the cerebral cortex and the cerebellar cortex, consist of layers that are folded or convoluted to fit within the available space.

The cerebellum is also involved in the automatization of some tasks, such as reading. citation The fact that some dyslexic children have motor task and balance impairments has been used as evidence for a cerebellar role in their reading difficulties.

The dentate nucleus, which in mammals is much larger than the others, is formed as a thin, convoluted layer of gray matter, and communicates exclusively with the lateral parts of the cerebellar cortex.

The first indications of compartmental structure came from studies of the receptive fields of cells in various parts of the cerebellar cortex.
