Neurotransmission 1. Chemical synapse(Classical Synapse) Predominates in the vertebrate nervous system 2.Non-synaptic chemical transmission 3. Electrical synapse Via specialized gap junctions Does occur. but rare in vertebrate NS Astrocytes can communicate via gap junctionsNeurotransmission 1.Chemical synapse (Classical Synapse) – Predominates in the vertebrate nervous system 2.Non-synaptic chemical transmission 3.Electrical synapse – Via specialized gap junctions – Does occur, but rare in vertebrate NS – Astrocytes can communicate via gap junctions
