MONTREAL — Grounding chronic illnesses and mental disorders in human DNA is like trying to tease out a giant riddle that’s complicated by the intricate relationship between biology and behaviour.
From the lab of CIFAR Fellow Michael Meaney (McGill University): Scientists have provided evidence that socioeconomic status affects family function and the development and function of brain regions that are critical for attention, learning and memory. Meaney's lab looks into how parenting produces lasting effects on cognitive and emotional development. His lab examined development in rats and found parental influences on the chemical, or 'epigenetic', signals that control the activity in the brain of genes that influence the connections between brain cells as well as learning and memory.
