Communication between neurons: neurotransmitters, receptors, and action potential

Abstract

In the body, a neurotransmitter is a chemical messenger that carries, amplifies, and balances impulses between neurons and target cells. An action potential is a quick series of voltage changes across a membrane that triggers neurotransmitter release from synapses' axonal terminals. After passing over the synaptic gap, the neurotransmitter binds to the receptor site on the opposing neuron, stimulating or inhibiting the receiving neuron or target cell with receptors that are membrane-bound receptor proteins. The permeability of each ion and the proportional ratio of extracellular to intracellular ions influence the action potential at any given time. This review will present current knowledge about neurotransmitters, receptors, and action potential work, their types, and working modalities, which would assist in better understanding interneuron communication complexity. This understanding is required for the development of effective drugs and treatment methods for neurological and psychological diseases caused by disruptions in neurotransmitter regulation.
