Properties of GABA receptors. GABA (g-aminobutyric acid) is the main inhibitory neurotransmitter in the central nervous system. The inhibitory action of GABA is mediated by the receptors present on the cell membrane, and results in a reduction of neuronal excitablity.At least three types of GABA receptors have been characterized.ABA (g-aminobutyric acid) is the main inhibitory neurotransmitter in the central nervous system.

The neurotransmitter at inhibitory synapses hyperpolarizes the postsynaptic membrane. The GABA A receptor is a ligand-gated chloride channel. Binding of GABA to the receptors increases the influx of chloride (Cl â) ions into the postsynaptic cell raising its membrane potential and thus inhibiting it. Arrival of an action potential at the synaptic knob opens Ca 2+ channels in the plasma membrane. 2  The influx of Ca 2+ triggers the exocytosis of some of the vesicles. 3  Their neurotransmitter is released into the synaptic cleft. 4  The neurotransmitter molecules bind to receptors on the postsynaptic membrane.
