Genetic Switch May Be Key to Human Brain’s Unique Abilities
Researchers have identified a genetic region, HAR123, that may help explain what makes the human brain unique. Acting as a transcriptional enhancer, HAR123 influences the development of neural progenitor cells, which give rise to neurons and glial cells, and plays a role in determining their ratio.
A Genetic Twist that Sets Humans Apart
Newswise — Research from scientists at University of California San Diego School of Medicine have shed new light on an age-old question: what makes the human brain unique? The team’s discovery comes from their investigation of human-accelerated regions (HARs) — sections of the human genome that have accumulated an unusually high level of mutations as humans have evolved. There is a lot of scientific interest in HARs, as they are hypothesized to …
