Neurophysiology — Flashcards

Lesions that involve the _____ cerebellum generally result in bi-lateral motor deficits affecting truncal and proximal musculature

The area postrema (chemoreceptor trigger zone) contains _____ receptors which are activated by substance P

Lesion of the _____ (midbrain) results in reduced levels of arousal and wakefulness (i.e. coma)

_____ cells inhibit deep nuclei of the cerebellum.

In _____ rigidity, if the anterior surface of cerebellum is removed the extensor rigidity is exaggerated

Associative learning is linked to _____ and cerebellum

The spinocerebellar tracts carry unconscious _____ input from the ipsi-lateral muscle spindles and GTOs to the cerebellum

In presynaptic facilitation, the _____ released at the axoaxonal ending increases the intraneuronal cAMP levels

Effects of Various Lesions and Brainstem Transections:Complete transection mid-pons with vagi _____ will lead to: Regular continued breating

The _____, also known as the vomiting center (located in the medulla) receives main inputs from: 1. GI tract 2. Vestibular system 3. Area postrema (chemoreceptor trigger zone)
