Neurotransmitter Systems

Meaning

Neurotransmitter Systems comprise the intricate network of chemical messengers that facilitate communication across synapses within the central and peripheral nervous systems. These small molecules transmit signals between neurons, regulating nearly all physiological and behavioral processes, including mood, sleep, cognition, and motor control. Their function is deeply intertwined with the endocrine system, as circulating hormones often modulate the synthesis, release, and receptor sensitivity of these neurotransmitters.
