After the ventrolateral preoptic nucleus is turned on,the neurotransmitter ____ is secreted.

D) benzodiazepine

Question

Quizplus · Accepted Answer

The ventrolateral preoptic nucleus (VLPO) is involved in the regulation of sleep and wakefulness. It promotes sleep by inhibiting the wake-promoting centers in the brain. This is done primarily through the release of the neurotransmitter GABA (gamma-aminobutyric acid), which has an inhibitory effect on brain activity. Therefore, choice A is the best answer. REM (choice B) is not a neurotransmitter but rather a stage of sleep. Dopamine (choice C) is a neurotransmitter associated with reward and motivation and is not primarily involved in sleep regulation. Benzodiazepine (choice D) is a class of drugs that enhance the activity of GABA and are commonly used as sleep aids, but they are not neurotransmitters.
