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.

Method pinpoints cell-specific effects of autism-linked mutations
The approach, which combines CRISPR with single-cell analyses of organoids, suggests that intermediate progenitor cells are especially vulnerable to mutations associated with 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.

Magnetic stimulation for autism: Q&A with Xujun Duan
A new individualized approach to transcranial magnetic stimulation may one day be an effective treatment for social and communication difficulties, if the results from Duan’s small preliminary trial pan out.

Skewed signaling in striatum may spawn repetitive behaviors
Synaptic changes in the brain region could drive a core trait of fragile X syndrome, a new mouse study suggests.

Is excess brain fluid an early marker of autism?
Brain scans of hundreds of infants suggest that up to 80 percent of those with autism have unusual amounts of cerebrospinal fluid. Researchers are studying how this might contribute to the condition.

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.

Food for thought: Neuronal fuel source more flexible than previously recognized
The cells primarily rely on glucose—rather than lactate from astrocytes—to generate energy, according to recent findings in mice.

Claims of necessity and sufficiency are not well suited for the study of complex systems
The earliest studies on necessary and sufficient neural populations were performed on simple invertebrate circuits. Does this logic still serve us as we tackle more sophisticated outputs?

Subthalamic plasticity helps mice squelch innate fear responses
When the animals learn that a perceived threat is not dangerous, long-term activity changes in a part of the subthalamus suppress their instinctive fears.
