There are no autism-specific genes, just brain genes
There is not yet a single example of a gene that, when mutated, increases the likelihood of autism but not of other neurodevelopmental conditions, including intellectual disability.

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.

Oxytocin shapes both mouse mom and pup behavior
Distressed pups emit distinct cries for help, which depend on oxytocin neurons in their hypothalamus.

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.

Michael Breakspear and Mac Shine explain how brain processing changes across neural population scales
Breakspear and Shine find a scale-free property of brain activity that is conserved across diverse species, suggesting that a universal principle of brain activity underlies cognition.
