Gut-Brain Axis Neurotransmitters

Meaning

Gut-Brain Axis Neurotransmitters refers to the complex array of signaling molecules, primarily neurotransmitters, that are synthesized or modulated within the gastrointestinal tract and participate in bidirectional communication with the central nervous system. This axis represents a vital neuroendocrine pathway linking gut health, the microbiome, and brain function. Key neurotransmitters, such as serotonin, dopamine, and GABA, are significantly produced or influenced by the enteric nervous system and gut microbiota, impacting mood, cognition, and stress response.
