Healthy Sleep May Rely on Long-Overlooked Brain Cells

Researchers at UCSF have confirmed that a different, long under-studied type of brain cell – astrocytes, named for their star-like shape – can influence how long and how deeply animals sleep.

Key Decision Point for Brain Development Identified

In a new study, UCSF and Stanford researchers have identified a central switch that appears to control when neural progenitor cells stop multiplying and start differentiating into mature neurons.

‘Hidden Biological Link’ Among Autism Genes Revealed in Study

A new study of autism risk genes by UCSF and UC Berkeley scientists implicates disruption in prenatal neurogenesis – a process in which specialized “progenitor” cells give rise to new brain cells – in the development of autism spectrum disorders.
