Alcohol and the brain

During a recent training event we got into a discussion on the effects of alcohol on our mental processes - which parts of the brain were affected and in what order?

It brought to mind cases of people who through brain damage have lost the use of the cerebral parts on their brain. While they cannot remember anything for more than a few seconds, they are still able to dress themselves, walk, eat and communicate. This is not entirely unlike a person who has too much to drink and cannot remember getting home, yet wakes up in bed wearing their pyjamas with the house securely locked.

It therefore strikes me that alcohol affects the cerebral brain first and the limbic brain second. In the case of the limbic system we do know that when people die from alcohol poisoning it is because the part of the brain responsible for consciousness and respiration closes down. The person therefore lapses into a coma, stops breathing and dies.

The early signs are possibly when the limbic systems priorities take over. These are often described as; fighting, fleeing, feeding and reproduction. Perhaps this is why people are more flirtatious in pubs, why arguments and fights are often fuelled by alcohol and why people have an urge to raid the fridge when they get back from the pub.

What do you think?
