N-arachidonyl-glycine (NAGly) prolongs the decay phase of currents induced by exogenous glycine, but not β-alanine. Bar chart of the amplitude and decay time of the membrane currents produced by exogenous application of glycine (100 µM) and β-alanine (100 µM). The data are expressed as a percentage ratio of the 5th : 3rd application of glycine, or β-alanine. NAGly (10–60 µM), or control ACSF (control) was added continuously after the 3rd application of glycine, or β-alanine (as in Figure 2). *P < 0.05, **P < 0.01, ***P < 0.001. ACSF, artificial cerebrospinal fluid.
