at concentrations > 0.1 mm the reversal potential became progressively more positive ( -55 to -50 mv ) .4 reduction of external chloride , with isethionate as the substitute anion , increased the amplitude of the depolarization.5 gaba reduced the amplitude of the excitatory postsynaptic potential produced by lateral olfactory tract stimulation , and occluded or reversed the subsequent depolarizing recurrent inhibitory postsynaptic potential.6 action potentials elicited by injection of depolarizing current or by focal antidromic stimulation were slowed and reduced in amplitude by gaba.7 the effects of gaba on membrane conductance ( potency = 1 ) were duplicated by 3-aminopropanesulphonic acid ( potency = 20 ) , beta-alanine ( 0.5 ) , beta-amino-n-butyric acid ( 0.5 ) , glycine ( 0.3 ) and l-2,4-diaminobutyric acid ( 0.2 ) .
