Disrupted cell skeletons may explain brain wiring changes in autism-linked condition
Neuronal axons ignore guidance cues after a mutation in the gene TSC2 disrupts signaling through RhoA, a protein regulated by many autism-linked genes.

Mice missing the autism-linked gene SHANK3 use more neurons to engage in social behavior than control mice do, reflecting a more disorganized, less efficient brain signaling network.
As cannabis prohibition slowly lifts in the United States, scientists and families in the autism community are increasingly turning to the drug and its constituent compounds to ease autism-related difficulties, including seizures and irritability.
Worms and zebrafish missing both copies of the gene CHD7 have disrupted cellular signaling, a dearth of inhibitory neurons and behavior changes — all of which are reversed by the stimulant drug ephedrine.
A test of binocular rivalry may distinguish between autism subtypes and help researchers screen the efficacy of certain drugs.
The investigational drug arbaclofen may right an imbalance between inhibitory and excitatory signaling in the animals’ brains.
Some neurons activate autism-linked genes when they fire, according to a new study.
Mice missing a copy of MAGEL2 have trouble discerning between a familiar mouse and an unfamiliar one; treating them with the social hormone vasopressin reverses this deficit.
Female mice missing a copy of the autism-linked gene MECP2 in a specific set of inhibitory neurons have a hard time heeding pups’ calls and herding litters.
People and mice with only one working copy of the autism gene SYNGAP1 may have trouble processing sights and sounds.
