Brain Development
A new genetic study has identified 331 genes essential for transforming stem cells into brain cells, including a novel gene linked to neurodevelopmental disorders. Led by scientists at the Hebrew University of Jerusalem, the research highlights how early genetic disruptions can lead to conditions like autism and developmental delay. The findings, published in Nature Neuroscience, also reveal patterns in how these disorders are inherited.

Researchers have identified four key turning points in brain wiring at ages 9, 32, 66, and 83, based on MRI scans of nearly 3,800 people. These shifts could explain variations in learning capacity and risks for conditions like dementia. The findings highlight how brain connections evolve through five distinct phases over a lifetime.
