The prefrontal cortex (PFC) region of the brain is involved in decision making. New rodent findings show that PFC neuron N-methyl-D-aspartic acid (NMDA) receptors are especially sensitive to concentrations of alcohol achieved during drinking. This suggests that alcohol's alteration of
Aripiprazole is currently approved to treat bipolar disorder as well as schizophrenia. A new study has found that it significantly and dose-dependently increases the sedative effects of alcohol and, to a lesser degree, decreases the euphoric effects of alcohol. Future
