GABA (gamma-aminobutyric acid) primarily functions as an inhibitory neurotransmitter in the mammalian central nervous system, including the rat's suprachiasmatic nucleus (SCN). It exerts its effects by binding to GABA receptors, which typically leads to the opening of chloride channels. This influx of chloride ions into the neuron hyperpolarizes the cell, making it less likely to fire an action potential, thereby inhibiting neuronal activity.
