Research into the neural basis of cataplexy has shown that during episodes of cataplexy:
A) neurons in the subcoerulear nucleus become inactive.
B) neurons in the magnocellular nucleus of the medulla become active.
C) neurons in the peribrachial area become active.
D) neurons in the subcoerulear nucleus become inactive and neurons in the magnocellular nucleus of the medulla become active.

Question

Quizplus · Accepted Answer

Research has shown that during episodes of cataplexy, neurons in the subcoerulear nucleus become inactive and neurons in the magnocellular nucleus of the medulla become active. This leads to a decrease in muscle tone and results in the characteristic symptoms of cataplexy, such as sudden episodes of muscle weakness or collapse. Neurons in the peribrachial area have also been implicated in the regulation of REM sleep, but their specific role in cataplexy is less clear.
