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.

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.

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.

Neuronal deafness to stress may add to protein surplus in fragile X
A protective pathway that pauses protein synthesis is muted in a mouse model of fragile X syndrome, according to a new study.

Trials of arbaclofen for autism yield mixed results
Autistic children taking the drug showed improvements in some behaviors but not in their social skills.

Cannabis compound rebalances signaling to quell seizures in mice
Cannabidiol (CBD) blocks the action of a molecule that drives an overexcitability feedback loop in a rodent model of epilepsy.

Unconventional optogenetics technique spurs long-lasting changes in neuronal activity
Conventional optogenetic manipulations to excite or inhibit neurons stop when the light switches off. A new approach makes the changes last.

Of mice and human interneurons: Q&A with Moritz Helmstaedter
People’s brains have a larger network of inhibitory interneurons than mouse brains do, according to a new study. Changes to that network could contribute to autism or other conditions, says lead investigator Moritz Helmstaedter.

Portrait of a research field: astrocytes in autism
Long cast in supporting roles in the brain, astrocytes are now emerging as primary players in certain characteristics of autism and related conditions.

Three autism-linked genes converge on tweaks to cells’ timing
Mutations in all three accelerate the maturation of inhibitory neurons, which could upset the brain’s balance of excitation and inhibition early in development.

At the credit crossroads: Modern neuroscience needs a cultural shift to adopt new authorship practices
Old heuristics to acknowledge contributors—calling out first and last authors, with everyone else in between—don’t work well for large collaborative and interdisciplinary projects, yet they remain the default.
