Neurochemical Responses

Meaning

Neurochemical responses are the complex cascade of physiological changes in the central and peripheral nervous systems mediated by the release, binding, and reuptake of neurotransmitters and neuromodulators. These chemical messengers, such as serotonin, dopamine, and gamma-aminobutyric acid (GABA), are fundamentally responsible for regulating mood, cognition, behavior, and the critical interaction between the brain and the endocrine system. Hormonal fluctuations significantly modulate the synthesis and sensitivity of these neurochemicals, creating a bidirectional communication loop.
