As an inhibitory neurotransmitter, GABA reduces a nerve cell's ability to send and receive chemical messages throughout the central nervous system. Fluctuating levels of GABA are linked to medical conditions including anxiety, autism, and Parkinson's disease. WebPrevious studies have indicated that γ-aminobutyric acid (GABA)- induced electrophysiological responses are enhanced by norepinephrine (NE) acting via postsynaptic β-adrenergic receptors. We found that local application of the NE high affinity uptake inhibitor desmethylimipramine (DMI) significantly potentiated GABA-induced …
