WebSep 8, 2014 · Schema of synaptic transmission. Upon arrival of a presynaptic spike, neurotransmitter spills into the synaptic cleft and is captured by postsynaptic receptors. B. Schema of a postsynaptic AMPA receptor of an excitatory synapse. When glutamate is bound to the receptor, sodium and potassium ions can flow through the membrane. … WebThis receptor translates the binding of the neurotransmitter, acetylcholine (ACh), into a rapid increase and subsequent decrease in the permeability of the endplate membrane to the passage of cations.. Inward flux of ions through the channel is passive, driven by electrochemical gradients across the receptor-containing membrane.
