When people make mistakes, activity in a part of the brain responsible for monitoring behavior increases, essentially sending an alarm signal to other parts of the brain indicating that something went wrong, said Bruce Bartholow, associate professor of psychology in the MU College of Arts and Science. Our study isnt the first to show that alcohol reduces this alarm signal, but contrary to previous studies, our study shows that alcohol doesnt reduce your awareness of mistakes it reduces how much you care about making those mistakes.COLUMBIA, Mo.

Study offers clue as to why alcohol is addicting

Drinking alcohol leads to the release of endorphins in areas of the brain that produce feelings of pleasure and reward, according to a study led by researchers at the Ernest Gallo Clinic and Research Center at the University of California, San Francisco.
The finding marks the first time that endorphin release in the nucleus accumbens and orbitofrontal cortex in response to alcohol consumption has been directly observed in humans.
Endorphins are small proteins with opiate-like effects that are produced naturally in the brain.
This is something that weve speculated about for 30 years, based on animal studies, but havent…

A low level of response (LR) to alcohol is a genetically influenced characteristic, or phenotype, that reflects at least in part a low brain response to alcohol, and carries significant risk for the later development of alcoholism. This study addressed the physiological underpinnings of a low and high LR, finding significant differences in brain activation during a cognitive task, possibly reflecting differences in the amount of brain activity used to deal with a cognitive challenge.
Results will be published in the January 2012 issue of Alcoholism: Clinical & Experimental Research and are currently available at Early…
