Synapses
· Electrical synapses
­ Presynaptic and postsynaptic cells
connected by gap junction where the
electrical current passes
­ voltage changes in the presynaptic cell
induces voltage changes in the
postsynaptic cell
­ rapid transfer of signals between cells
­ found mainly in invertebrates and lower vertebrates
· Chemical synapses
­ Chemical released by presynaptic cells
bind to receptors on postsynaptic cells
­ neurotransmitters either initiate an
