WebAug 21, 2024 · Neurones talk to each other by passing chemical signals called neurotransmitters across small gaps called - synapses. Presynaptic neurone release neurotransmitter which then diffuses across the synapse before binding to the receptor on the postsynaptic neurone. This process is called synaptic transmission. The binding of a … WebInstead, a given neurotransmitter can usually bind to and activate multiple different receptor proteins. Whether the effect of a certain neurotransmitter is excitatory or inhibitory at …

WebIn short, the summation of EPSPs and IPSPs by a postsynaptic neuron permits a neuron to integrate the electrical information provided by all the inhibitory and excitatory synapses acting on it at any moment. Whether the sum of active synaptic inputs results in the production of an action potential depends on the balance between excitation and inhibition. WebNational Center for Biotechnology Information
