GABA crystals. Polarised light micrograph of gamma-aminobutyric acid (GABA). GABA is an inhibitory neurotransmitter (nerve signalling chemical) that regulates the excitability of all nerve cells. In humans, it is directly responsible for maintaining muscle function. It also has a key role in regulating the growth of embryonic and neural stem cells.
