Mutation in top autism-linked gene may alter eye reflex
The discovery could help clinicians diagnose children who carry mutations in the gene, called SCN2A, and gauge their responses to potential therapies.

Some social issues in DYRK1A model mice stem from faulty inhibitory circuits
Alterations in inhibitory circuits and difficulties in social recognition characterize mice missing one copy of DYRK1A, a gene linked to autism.

UBE3A’s link to synaptic pruning bolstered by fly study
Increasing or reducing the levels of the UBE3A gene, which is associated with autism and autism-related syndromes, results in altered patterns of synaptic pruning — a process that snips away brain cell connections.

Head size parts autism into two major subtypes
An imbalance in the number of excitatory neurons in early brain development may account for the difference.

New test taps nose pokes as a proxy for social motivation in mice
Over one hour, a particularly motivated mouse poked its nose 350 times into a hole in the test chamber in the hopes of meeting a playmate.

Rat neurons thrive in a mouse brain world, testing ‘nature versus nurture’
Neurons from the two rodents can wire up together to form functional circuits—all while maintaining some species-specific properties, two new studies show.

It’s past time to stop using the Reading the Mind in the Eyes Test
The widely used measure of “theory of mind” needs to be re-examined, along with the long-standing claim that autism is linked to a lack of this ability.
