GABA is the primary inhibitory neurotransmitter in the brain and mediates several processes, including learning and memory. Activating or inhibiting GABA receptors allows for the examination of the effects of altered GABAergic signaling on these processes. The two main receptors, GABAA and GABAB, each have a different mechanism of action when activated, thus they may contribute differentially to learning and memory. The metabotropic GABAB receptor responds with the activation of several intracellular signaling cascades, which provide long-lasting inhibitory effects that primarily mediate network function. Conversely, the GABAA receptor is an ion channel that contributes more immediate inhibitory effects through the …
