Neurophysiology — Flashcards

Resting membrane potential of a _____ is -70 mV

_____ bladder results from lesions above the sacral spinal cord levels

In _____ rigidity, the brainstem pathways are unregulated due to loss of effect of rubrospinal and corticospinal tract

The Cushing reaction is a triad of _____, bradycardia, and respiratory depression due to increased intracranial pressure

In _____ rigidity, the upper and lower limbs show extension due to loss of excitation by corticospinal and rubrospinal fibres on flexor alpha-motor neurons of spinal cord; and corticoreticular fibres on reticular formation of medulla.

In the indirect basal ganglia pathway, inhibition of the globus pallidus externus leads to _____ of neurons of the subthalamic nucleus

Lesions that involve the _____ cerebellum produce a number of dysfunctions, mostly involving the ipsi-lateral extremities (distal musculature)

Hint: medial or lateral

The _____ area of the hypothalamus is responsible for satiety

_____ describes a change from areflexia --> hyporeflexia --> hyperreflexia in patients with spinal cord injuries

Lesions to the _____ may result in:- deficits in verbal memory (ex. word recognition) if the dominant lobe is affected- deficits in nonverbal memory (ex. musical ability) if the nondominant lobe is affected
