It’s all in a good night’s sleep

Making sure school-aged kids get to sleep at a regular hour is often a struggle for parents. But a study by researchers at McGill University and the Douglas Mental Health University Institute in Montreal suggests it’s well worth the effort: the researchers found that a good night’s sleep is linked to better performance in math and languages – subjects that are powerful predictors of later learning and academic success.

Alcoholism: effects on the brain's dopamine system

Research from McGill University suggests that people who are vulnerable to developing alcoholism exhibit a distinctive brain response when drinking alcohol, according to a new study by Prof. Marco Leyton, of McGill University’s Department of Psychiatry. Compared to people at low risk for alcohol-use problems, those at high risk showed a greater dopamine response in a brain pathway that increases desire for rewards. These findings, published in the journal Alcoholism: Clinical & Experimental Research, could help shed light on why some people are more at risk of suffering from alcoholism and could mark an important step toward the development of treatment options.
