AI Reveals How Brain Cells Evolved Over 320 Million Years

A new study reveals how AI-driven deep learning models can decode the genetic regulatory switches that define brain cell types across species. By analyzing human, mouse, and chicken brains, researchers found that some brain cell types remain highly conserved over 320 million years, while others have evolved uniquely.

Decoding Brain Evolution

A new center headed by neurobiologists at Harvard is looking to unravel some long standing mysteries of the human brain. Researchers, backed by a $10 million grant, hope to shed light on brain development, evolution and human behavior. The funding will allow researchers to use ancient DNA to track frequency of genetic changes and provide a better understanding of the nature of human adaptation.
