Jump-starting growth signaling reverses microcephaly in autism mouse model

by  /  29 April 2021

A genetic therapy and an existing drug both restore typical brain size in mice missing DYRK1A, a top autism candidate gene, in the cerebral cortex, a new study shows. The animals typically have smaller brains than controls.

Thin insulation may explain atypical cortical thickness seen in autism

by  /  23 April 2021

Differences in myelin, the insulation that surrounds neuronal projections, may shade measurements of cortical thickness on brain scans, a new study suggests.

Neuron ‘skeleton’ may explain impact of autism-linked gene mutation

by  /  16 April 2021

Mutations in CUL3, a gene strongly linked to autism, may cause differences in brain structure by disrupting cytoskeleton proteins, according to a new study.
