Scientists discover 'fickle' DNA changes in brain

Johns Hopkins scientists investigating chemical modifications across the genomes of adult mice have discovered that DNA modifications in non-dividing brain cells, thought to be inherently stable, instead underwent large-scale ...

Neurobiologists restore youthful vigor to adult brains

They say you can't teach an old dog new tricks. The same can be said of the adult brain. Its connections are hard to change, while in children, novel experiences rapidly mold new connections during critical periods of brain ...

Effects of maternal smoking continue long after birth

Early exposure to nicotine can trigger widespread genetic changes that affect formation of connections between brain cells long after birth, a new Yale-led study has found. The finding helps explains why maternal smoking ...

Sociability may depend upon brain cells generated in adolescence

Mice become profoundly anti-social when the creation of new brain cells is interrupted in adolescence, a surprising finding that may help researchers understand schizophrenia and other mental disorders, Yale researchers report.
