Artificial intelligence drew much inspiration from the human brain but went off in its own direction. Now, AI has come full circle and is helping neuroscientists better understand how our own brains work.

Study reveals concussion’s complex nature

Concussion is a major public health problem, but not much is known about the impacts that cause concussion or how to prevent them. Bioengineer David Camarillo and colleagues suggest that the problem is more complicated than previously thought.

Kids see words and faces differently from adults
