Neanderthal genes give clues to human brain evolution

A distinctive feature of modern humans is our round (globular) skulls and brains. Researchers report that present-day humans who carry particular Neanderthal DNA fragments have heads that are slightly less rounded, revealing genetic clues to the evolution of modern brain[…]

Parents' brain activity 'echoes' their infant's brain activity when they play together

Research shows for the first time that when adults are engaged in joint play together with their infant, the parents' brains show bursts of high-frequency activity, which are linked to their baby's attention patterns and not their own.
