Gaba

GABA (gamma-aminobutyric acid) is a major inhibitory neurotransmitter: it tends to quiet neuronal activity and helps balance excitatory signaling from glutamate. 1

The discussion also links GABA to several topics: ketogenic metabolism may increase GABA activity; alcohol can increase GABA signaling but may be followed by rebound excitability; and GABA signaling is discussed in relation to anxiety, seizures, sleep, and OCD. 2 3
