Alcohol addiction is a costly and detrimental chronic relapsing disorder, characterized by compulsive alcohol use despite the negative consequences; it is thought to be associated with aberrant learning and memory processes [1,2].
The NMDA-type glutamate receptor (NMDAR) plays an essential role in synaptic plasticity and learning and memory [3,4].
Not surprisingly, it is well established that the NMDAR is a major target of alcohol (ethanol) in the brain and has been implicated in ethanol-associated phenotypes such as tolerance, dependence, withdrawal, craving, and relapse [5,6].
This chapter focuses on studies elucidating molecular mechanisms that underlie ethanol’s actions on the NMDAR, and discusses the physiological and behavioral consequences of ethanol’s actions.
Finally, we summarize information regarding the potential use of modulators of NMDAR function as medication to treat the adverse effects of alcoholism.
