The Body Keeps Score: epigenetics

A Sock Mystery at my house.   Onesies.





One of the most cited experiments in epigenetics was conducted by McGill University researcher Michael Meaney, who studies newborn rat pups and their mothers.
He discovered that how much a mother rat licks and grooms her pups during the first twelve hours after their birth permanently affects the brain chemicals that respond to stress—and modifies the configuration of over a thousand genes.
The rat pups that are intensively licked by their mothers are braver and produce lower levels of stress hormones under stress than rats whose mothers are less attentive.
They also recover more quickly—an equanimity that lasts throughout their lives.
They develop thicker connections in the hippocampus, a key center for learning and memory, and they perform better in an important rodent skill—finding their way through mazes.



One response to this post.

    Seems early bonding so important in our emotional development.
    I was separated at birth from my mother for one month. Premature in times where not held much. Never felt a closeness until adult.

    ….perhaps same colored socks for boys?
