What substance can act as a retrograde messenger to suppress release of GABA to contribute to LTP?
A)acetylcholine
B)endocannabinoid
C)carbon monoxide
D)norepinephrine

Question

Quizplus · Accepted Answer

Endocannabinoids can act as retrograde messengers in the brain, inhibiting the release of neurotransmitters such as GABA. This can contribute to the induction of long-term potentiation (LTP) in neurons, which is thought to underlie learning and memory processes. Acetylcholine and norepinephrine are not typically involved in retrograde signaling mechanisms in the brain, and carbon monoxide is not a known neurotransmitter or retrograde messenger.
