Overall, periadolescent binge-like drinking decreased gene expression for certain NMDA receptor subunits in the DRN, but increased particular AMPA, delta, and kainate receptor subunits within this region as well. Ethanol self-administration by adult P rats did not downregulate any NMDA receptor subunits in the AcbSh but did upregulate an AMPA, delta, and NMDA-receptor subunit.
