The role of neurotransmitters in signaling between neurons is essential for communication within the nervous system. These chemical messengers are released from the axon terminals of one neuron and bind to receptors on the dendrites of another neuron, facilitating the transmission of signals across the synapse. Neurotransmitters can either stimulate or inhibit neuronal activity, influencing mood, behavior, and numerous physiological processes. Understanding neurotransmitter function is crucial in neuroscience, as it provides insights into how neural communication affects various aspects of health and disease.
