WebMany of these receptors contain an ion channel capable of passing positively-charged ions either into or out of the cell (such receptors are called ionotropic receptors ). At excitatory synapses, the ion channel typically allows sodium into the cell, generating an excitatory postsynaptic current. WebThe receptors typically influence the opening or closing of ion channels. 9 Neurotransmitter Receptor Types Ionotropic receptors Metabotropic receptors • Ion channels • Not ion channel • Direct change in ion movement across • Induce signalling cascade in the the plasma membrane of postsynaptic postsynaptic cell that leads to changes in cell ion … birds gotta fly vintage facebook https://comperiogroup.com
