Even low alcohol concentra-tions can inhibit the excitatory activity of the NMDA receptor. This inhibition of NMDA receptor function may be one of the mechanisms contributing to fetal alcohol syndrome and other more subtle developmen-tal abnormalities. Moreover, alcohol-induced impair-ment of the NMDA receptor may ...
