Contrast the location and function of autoreceptors with postsynaptic receptors
What will be an ideal response?
Answer: Autoreceptors often act to feed back negatively onto either synthesis of
neurotransmitters or to inhibit the release of transmitter; these are metabotropic effects involving second messengers. Postsynaptic receptors bind transmitter and either directly control an ion channel (ionotropic) or use a second-messenger to control an ion channel (metabotropic).
