Neurophysiology — Flashcards

Withdrawal reflex: The prolonged after-discharge in _____ reflex is due to reverberating circuits among the interneuronal cells

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

Long-term _____ is classically seen in the hippocampus

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.

The _____ area of the hypothalamus is responsible for satiety

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

Hint: medial or lateral

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

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

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