I know the effect from my former me and many of you might have experienced it, too. When drinking a lot of alcohol one tends to forget minutes to hours of what happened. Why does this happen? Are the cells storing the info dying? Is there a problem with passing the info down to the cells that store them? Are we just tired late at night and this is the reason why we cannot remember? Please help me to understand.

Alcohol has many effects in the brain so it’s hard to pin down a mechanism. But it blocks one called glutamate in a part of the brain called the hippocampus. The hippocampus is involved in making new memories so when that’s out of commission, new memories are temporarily not made. Older established memories are unaffected. So that’s the memory blackout period.
