Summary
Gamma-aminobutyric acid (GABA) is the major inhibitory neurotransmitter in the brain. The primary precursor of GABA is glutamate, the major excitatory neurotransmitter in the brain. Glutamate is converted into GABA via glutamate decarboxylase (GAD). GABA-transaminase (GABA-T) metabolizes GABA to succinic semialdehyde, which is rapidly metabolized to succinic acid by succinic semialdehyde dehydrogenase (SSADH) and then enters the tricarboxylic acid (TCA) cycle (Figure 23.1).
