Postsynaptic terminal function

WebThe presynaptic terminals stimulated by neural spikes release neurotransmitters that bind to receptors on the postsynaptic terminal, generating an excitatory postsynaptic current (EPSC) and inducing memory formation. 29,30 Fig. 1b illustrates a dual-gate electrolyte gated transistor inspired by the biological counterpart, where the two gates and the … WebSynaptic vesicles from the terminal of the presynaptic neuron produce neurotransmitters at the synaptic cleft when the action potential reaches the terminals. Neurotransmitters bind to postsynaptic membrane receptors enabling voltage-gated channels to …
