Bottom: 1, Neurotransmitter is released from presynaptic cell into synapse. 2, Neurotransmitter, recognized by receptor cell, causes channel to open, and ions are exchanged. 3, Exchange of ions causes impulse, which causes reaction in receptor cell. 4, Neurotransmission has taken place, receptor channel closes, and neurotransmitter returns to presynaptic membrane (reuptake).
