Molecular mechanisms: Autism protein connects neurons
An autism-linked protein called CASPR2 promotes the development of dendrites, the bushy structures atop neurons that receive signals from other neurons, according to a study published 30 October in Proceedings of the National Academy of Sciences. Lowering CASPR2 levels leads to sparse dendrites and few synapses, the junctions between neurons.

Molecular mechanisms: Stress pathway dysregulated in autism
Two studies report abnormalities in the system that mediates the body’s response to stress in two mouse models of autism-related diseases: Angelman syndrome and Rett syndrome. The results were published in the April issue of Human Molecular Genetics.

Molecular mechanisms: Autism gene tied to neuronal wiring
An autism-linked protein helps wire neurons together, according to two studies published in late September.

Molecular mechanisms: MeCP2 loss ups signal strength
A study using action potentials, the electrical impulses that trigger signaling, shows that neurons lacking MeCP2, the Rett syndrome protein, have stronger neuronal signals compared with controls, according to a study published in the July Journal of Neurophysiology.

Molecular mechanisms: Neuroligin-4 induces synapses in a dish
Neuroligin-4, a protein associated with autism, is located at synapses — the junctions between neurons — that inhibit signals in the brain, according to a study published in February in the Proceedings of the National Academy of Sciences. The protein can also single-handedly induce neurons derived from human stem cells to form synapses, according to another study in the same issue.

Bespoke photometry system captures variety of dopamine signals in mice
The tool tracks the excitation of an engineered protein that senses dopamine’s absolute levels, including fast and slow fluctuations in real time, and offers new insights into how the signals change across the brain.

What infant fMRI is revealing about the developing mind
Cognitive neuroscientists have finally clocked how to perform task-based functional MRI experiments in awake babies—long known for their inability to lie still or take direction. Next, they aim to watch cognition take shape and settle a debate about our earliest memories—with one group publishing a big clue today.

Molecular changes after MECP2 loss may drive Rett syndrome traits
Knocking out the gene in adult mice triggered up- and down-regulated expression of myriad genes weeks before there were changes in neuronal function.
