Answer
Neurotransmitters serve as chemical messengers that facilitate communication between neurons in the nervous system. These specialized molecules are synthesized, stored, and released into the synaptic cleft, where they bind to receptors on the postsynaptic neuron, transmitting electrical or chemical signals. The precise release, binding, and reuptake of neurotransmitters are crucial for brain functioning, influencing processes like mood, cognition, and movement.
