Why some black out after drinking

Do you often experience a blackout after a night of heavy partying? Then, it could be that your brain has been wired differently , scientists say.

Researchers at the University of Pennsylvania in the US found differences in brain activities among individuals prone to alcohol-induced fragmentary blackouts compared with people who don't experience such conditions.

They found that the two "party types" did not differ in performance on a memory task while sober, but did exhibit different brain-response patterns after alcohol intoxication . "It could be that their brains are just wired differently . Or it could be underlying things going on, like differences in dopamine levels," study author Reagan Wetherill said.

"Some people are made differently and are able to handle things such as alcohol and others just aren't ."
