GluN2B transmission and NMDAR metaplasticity in adult male mice with a history of AIE following an ethanol challenge. (A) Protocol used to evaluate whether an ethanol challenge (single 16-h vapor chamber session, EtOH) given during a prolonged period of abstinence would re-engage NMDAR plasticity induced by AIE (AIE-EtOH) relative to air controls (Air-EtOH). (B) Time course of NMDAR-EPSC peak amplitudes following a 10-min application of Ro 25–6981. (C) Plot of the summation index across stimulation frequencies and treatments demonstrating that an alcohol re-exposure had no effect on the temporal summation of NMDA-EPSCs in adult males with a history of AIE. All data points indicate mean ± SEM.
