Neurophysiology — Flashcards

GABA-_____ receptors appear to mediate presynaptic inhibition via a G-protein that produces an increase in K+ conductance.

The _____ is responsible for the synthesis of acetylcholine

_____ bladder is seen above S2 level of injury

In both the direct and indirect basal ganglia pathways, neurons from the cerebral cortex lead to _____ of neurons of the striatum

Withdrawl reflex:In the _____ reflex, the contraction occurs 0.2-0.5 seconds after flexor reflex in the other limb and the after-discharge is prolonged.

In the indirect basal ganglia pathway, the neurons of the striatum lead to _____ of neurons of the globus pallidus externus

Lesion of the _____ area of the hypothalamus results in hyperphagia

Layers of the cerebellum:The only output from the cerebellar cortex is _____ from the Purkinje cells to the deep cerebellar nuclei.

Hint: excitatory/inhibitory

PO2 _____ cerebral perfusion pressure only when < 50 mmHg

Medial motor pathways:_____ reticular nuclei transmit inhibitory signals to the antigravity/extensor muscles by way of the medullary reticulospinal tract, located in the lateral column of the cord.
