Synapses and Neurotransmitters Notes
... Neurotransmitter release requires Ca2+ ions Normally, the concentration of Ca2+ in the pre-synaptic neuron l is kept very low (by the action of a Ca pump). The arrival of an action potential at the axon terminus opens voltage-gated Ca channels, and Ca2+ ions rush inside the pre-synaptic neuron The i ...
