Gut hormone increases response to food

Ghrelin promotes conditioning to food-related odours

The holiday season is a hard one for anyone watching their weight. The sights and smells of food are hard to resist. One factor in this hunger response is a hormone found in the stomach that makes us more vulnerable to tasty food smells, encouraging overeating and obesity. New research on the hormone ghrelin was published on Dec. 4, 2018, led by Dr. Alain Dagher’s lab at the Montreal Neurological Institute and Hospital of McGill University.

Lack of joy from music linked to brain disconnection

Have you ever met someone who just wasn’t into music? They may have a condition called specific musical anhedonia, which affects three-to-five per cent of the population.

Researchers at the University of Barcelona and the Montreal Neurological Institute and Hospital of McGill University have discovered that people with this condition showed reduced functional connectivity between cortical regions responsible for processing sound and subcortical regions related to reward.
