Neuroscience made simpler.
The brain, explained — reference entries and stories, written and reviewed by people who study it.
In focus
People who feel closer to their dog than to most humans aren’t cold or antisocial. Research suggests that when a dog and its owner look into each other’s eyes, both brains release the same bonding hormone that ties a mother to her baby
Dying of a broken heart isn’t just a saying, because in the first three months after losing a husband or wife, widows and widowers had a 66% higher risk of dying themselves, a Harvard study of more than 12,000 older adults found
