Paternal mice bond with offspring through touch: Males generate new brain cells and form memories leading to positive relationships

New research by neuroscientists shows that paternal mice that physically interact with their babies grow new brain cells and form lasting memories of their babies. A recent study found that when paternal mice interact with their newborn babies, new brain cells develop in the olfactory bulb, the part of the brain responsible for sense of smell, and in the hippocampus, which is responsible for memory.
