How does alcohol affect adolescent and young adult brains?
Furthermore, alcohol consumption during adolescence may alter measures of brain functioning, such as blood flow in certain brain regions and electrical brain activities. Not all adolescents and young adults are equally sensitive to the effects of alcohol consumption, however.
What is the relationship between alcohol and cognitive control?
Alcohol and cognitive control is an important subject. Adolescence is a major period for the development of cognitive control. And most young people begin experimenting with alcohol as they enter adolescence. Cognitive control is the ability to to choose an appropriate behavior over one that you’ve decided is inappropriate.
