Figure 3: Electrophysiological recordings of inward currents produced by glycine in oocytes containing alpha1 or alpha2 receptors in the absence and presence of ethanol. Oocytes were perfused with ethanol (100 mM) for 1 min prior to the application of ethanol (100 mM) plus glycine (alpha1: 25 uM) or glycine (alpha2: 50uM) for 30 sec.
