Gamma (γ) -aminobutyric acid (GABA) is the major inhibitory neurotransmitter found in

the mammalian central nervous system. Its effect stems from its ability to cause the opening of ion channels which causes an influx of negatively charged chloride ions or an efflux of positively charged potassium ions. This hyperpolarization of the neuron lowers the threshold for neuronal firing. This has an overall inhibitory effect on neurotransmission, decreasing the excitability of the neuron and diminishing the likelihood of a successful action potential occurring. There are two classes of GABA receptor: ligand-gated GABAA receptor (GABAAR) and metabotropic GABAB receptor (GABABR). The GABAAR …
