Sensory memory — which includes information about everything we see, hear, smell, taste and touch — lasts for one to two seconds. These individuals may or may not experience blackouts or brownouts; again, in some instances, the brain may not be prone to this symptom.

In humans the amount of alcohol that triggers a blackout varies from person to person. En bloc blackouts are when the part of the brain responsible for storing short-term memories stops functioning while drinking. A memory is made and stored before it can be retrieved. Loss of Short Term Memory as a Predictor of the Alcoholic “Blackout.” Retrieved from, Jacobson, R. (1986, August).

Thats because the brains ability to create long-term memories isnt affected as much by blood alcohol content as it is by rapid rises in that level.

These people may not realize that they’re even missing or forgetting a portion of their evening until the memory is triggered in this way.

They have also been known to walk home, brush their teeth, eat meals, or go through other normal behaviors. The reverse is also true: Some brains may be resistant to blacking out.
