Gaba deactivation
WebGABAergic IPSCs have a relatively slow decay (deactivation) that appears to result from GABA A receptor channel openings that occur well beyond the predicted duration of free GABA at central synapses. Open and desensitized states have been suggested to prevent dissociation of agonist from the receptor, thus prolonging deactivation. WebA selective agent for the activation of GABA A receptors without effect on GABA B or GABA C receptors is 4-aminotetrolic acid ( Fig. 2 ), an analog of GABA containing a triple bond that holds it in a fully extended conformation ( Johnston, 2016 ). It is an inhibitor of GABA uptake and of GABA transaminase. View chapter Purchase book
