Mapping Out Genetic ‘Switches’ Behind Human Brain Evolution
n assess their effect on gene expression and neurogenesis.
UCLA researchers mapped the genetic on/off switches driving neurogenesis in the brain and shaping the expansion of human cortex. The image shows schematics of slices of the mouse, macaque and human brain to scale. The interior of the slices is represented by a mouse brain. Strands of chromatin, where the on/off switches reside, are interlaced across the brains. NeuroscienceNews.com image is credited to Luis de la Torre-Ubieta/UCLA Health.

Researchers have created a map of gene regulation in human cortical neurogenesis. The study reveals a number of factors that govern brain growth and the development of some brain disorders.
