PTEN problems underscore autism connection to excess brain fluid
Damaging variants in the autism-linked gene cause congenital hydrocephalus—a buildup of cerebrospinal fluid in the brain—by turbocharging a downstream signaling pathway that promotes the growth of cells, according to a new study.

U.S. health agency purge includes 10 lab heads at National Institute of Neurological Disorders and Stroke
The reasons for selecting these researchers—who have led work on neuronal migration, dopamine receptors in neuronal signaling and the structure of ion channels, among other areas—remain unclear.
