Autoreceptors also function to:
A)enhance synthesis and release of neurotransmitter.
B)reduce the synthesis and additional release of neurotransmitter.
C)reduce binding at the postsynaptic receptor and produce inhibition at the synapse.
D)augment synaptic transmission.

Question

Quizplus · Accepted Answer

Autoreceptors are located on presynaptic neurons and sense the level of neurotransmitter in the synaptic cleft. When the level of neurotransmitter is high, autoreceptors reduce the synthesis and additional release of neurotransmitter to prevent excessive levels of neurotransmitters in the synaptic cleft. This negative feedback mechanism helps to regulate the amount of neurotransmitter released and maintain appropriate levels of neurotransmitter activity in the CNS.
