An example of "autoreceptors" in the CNS is:
Autoreceptor is a presynaptic receptor; binding of the NT with autoreceptor inhibits fuher secretion of the transmitter. a2-receptor for NE is an example of autoreceptor. NMDA receptor for glutamate is a voltage + ligand gated channel. Nicotinic AChR is a non-specific cation channel. GABA-C receptors are found exclusively in the retina; they are ionotropic receptors.
