New mouse brain atlas traces connections in fine detail

by  /  13 January 2021

A new wiring diagram of the mouse brain could help autism researchers better study how brain connections vary in mice with different genetic backgrounds.

Brain response to facial features may lag in autistic people

by  /  13 January 2021

Looking at eyes, noses and mouths may prompt slower recognition in the brains of autistic people than in those of non-autistic people.

Imaging study casts doubt on cerebellum’s role in autism during infancy

by  /  13 January 2021

Connections between the cerebellum and brain networks do not seem to contribute substantially to the emergence of autism traits.

Motor skills, brain volume affected in mouse model of DDX3X syndrome

by  /  13 January 2021

Mice missing one copy of the autism-linked gene DDX3X have smaller brains and worse motor skills than mice with both copies of the gene, according to a new unpublished study.

Zebrafish lacking oxytocin receptors skip school

Cerebellum alterations crop up in mice missing autism gene

by  /  12 January 2021

Deleting the autism-linked gene CNTNAP2 from mice leads to distinct cellular and electrical changes in the cerebellum, according to two unpublished studies presented virtually today at the 2021 Society for Neuroscience Global Connectome.

Studies hint at effects of aging on autistic brains

by  /  12 January 2021

People with autism or autism traits may be especially vulnerable to brain aging and cognitive decline, two studies suggest.

Dopamine neurons may dampen social behavior in mouse model of autism

by  /  12 January 2021

Mice missing a copy of the autism-linked gene PTEN show a reduced preference for social interaction, possibly due to atypically large, overconnected dopamine neurons. Easing the overconnection may alleviate this trait.

Environment may have outsized effect on brain structure in autism

by  /  12 January 2021

Environmental factors influence brain structure in autistic children more than in non-autistic children, according to an analysis of imaging data from twins.
