Question

Quizplus · Accepted Answer

Fast excitatory postsynaptic potentials (EPSPs) are produced at both nicotinic cholinergic receptors, which are ionotropic receptors found at neuromuscular junctions and in the nervous system, and AMPA receptors, which are a type of glutamate receptor also ionotropic and crucial for fast synaptic transmission in the brain. Alpha-adrenergic receptors, on the other hand, are metabotropic and generally associated with slower postsynaptic responses.
