ScienceDaily (May 9, 2010) — New research from neuroscientist Samuel Weiss, PhD, director of the Hotchkiss Brain Institute at the Faculty of Medicine, shows that paternal mice that physically interact with their babies grow new brain cells and form lasting memories of their babies. The study is published online in the journal Nature Neuroscience...
Previous research has shown that adult humans also have the capacity to generate new brain cells in the olfactory bulb and the hippocampus and that human fathers exhibit more affection and attachment and fewer ignoring behaviors toward children whose smell they can identify.
"What we have found has implications for long-term mental health," says Weiss. "Our work shows that social interactions foster healthy brains and healthy brains foster positive social interactions, demonstrating a positive feedback loop. Our findings support the idea that physical interactions between fathers and their offspring may be a critical component for developing healthy relationships and a healthy society."
