Developmental disorders should be viewed as continuum
Intellectual disability, autism, epilepsy and schizophrenia should be considered part of a spectrum of developmental brain dysfunction, says David Ledbetter.

International scientific collaboration is more necessary—yet more challenging—than ever
These partnerships accelerate neuroscience by enabling researchers to share resources and expertise, as well as generate more relevant and reproducible results. But new federal funding restrictions in the United States are putting such collaborations in jeopardy.

Sensory gatekeeper drives seizures, autism-like behaviors in mouse model
The new work, in mice missing the autism-linked gene CNTNAP2, suggests a mechanism to help explain the overlap between epilepsy and autism.
