GABAB receptor

GABAB receptors are specialized proteins found in the brain and nervous system that respond to the neurotransmitter GABA (gamma-aminobutyric acid). They help regulate neural activity by calming nerve signals, promoting relaxation and reducing over-excitement. When GABA binds to GABAB receptors, it triggers processes that make neurons less likely to fire, contributing to a balance between excitation and inhibition in the brain. This mechanism is critical for controlling anxiety, sleep, and muscle relaxation, and is targeted by certain medications to treat conditions like anxiety and epilepsy.
