ionotropic receptors (ligandgated channels)
Allow movement of ions across membrane
through a gate that opens when neurotransmitter
binds; mediate fast behavior
Involved in signal transduction cascades: Alter internal chemistry, Can modulate ion channels, Can result in alteration of protein synthesis via effects on gene transcription
Most common type is the G protein-coupled receptor
Couples a neurotransmitter (1st messenger) to an
effector protein via a G Protein (guanosine
phosphate binding protein) attached to the receptor
second messenger (G-protein coupled receptor)
can activate other enzymes resulting in a
transduction cascade that can affect many chemical
change in production of proteins; Formation of new receptors, enzymes, trophic
Nuclear hormone receptors
bind to steroids (corticosteroids, mineralcorticoids, sex steroids, vitamin D), thyroid hormone
