Professor Leclair is giving a lecture on autoreceptors. She tells the class that _____.
A) the activity of autoreceptors results in GABA being released into the synapse
B) autoreceptors increase the amount of calcium that enters the axon terminal
C) activated autoreceptors decrease neurotransmitter release
D) the activity of autoreceptors results in glutamate being released into the synapse

Question

Quizplus · Accepted Answer

Autoreceptors are a type of receptor located on the presynaptic neuron that respond to the neurotransmitter released by that neuron. When activated, autoreceptors can decrease the amount of neurotransmitter release, which can lead to a decrease in overall neural activity. This feedback system helps regulate neurotransmitter concentration and maintain neural balance. Therefore, choice C is correct while the other options are incorrect.
