  • Mothers prefer to hold their babies on the left. Wild mammals seem to like keeping their young on that side too, at least when fleeing predators. Now it seems the young of many mammals prefer to approach their mother from one particular side, as well. The explanation may lie in the contrasting talents of each half of the brain. In mammals, the brain's right hemisphere is responsible for processing social cues and reinforcing relationships. This half of the brain is also the one that receives signals from the left eye.
