→→ GABA is an inhibitory neurotransmitter, meaning it reduces neural activity and calms the central nervous system (CNS).
It works by binding to GABA-A receptors on neurons, opening chloride ion (Cl) channels.
Chloride ions enter the neuron, making it more negatively charged and less likely to fire (produce an action potential). This reduces brain activity, creating a calming effect that lowers anxiety.
