Summary: A new study reveals that human accelerated regions (HARs)—segments of DNA that evolved much faster than expected—may be key to the brain’s advanced cognitive abilities. Researchers compared human and chimpanzee neurons and found that HARs drive the growth of multiple neural projections, which enhance communication between brain cells.When human...

Summary: A new study shows that brain activity in small groups can predict large-scale decision-making. Using fMRI, researchers found that activity in the Nucleus Accumbens (NAcc) during initial affective responses consistently aligned with choices made by thousands of online participants.While individual decisions varied, the early brain responses were broadly shared,...
