How are outer hair cells most likely inhibited by medial efferents?

Question

Quizplus · Accepted Answer

CMedial efferent inhibition of outer hair cells is primarily achieved through cholinergic mechanisms. The correct mechanisms involve (B) cholinergically generated inhibitory postsynaptic potentials (IPSPs) that lower the membrane potential through a change in the driving force of potassium, and (C) cholinergically generated IPSPs that result in no production of second messenger (e.g., cAMP) through inhibitory G protein (Gi) coupled receptors (GPCRs). These processes help modulate the activity of outer hair cells, contributing to the fine-tuning of auditory signals.
