How to avoid common pitfalls when parsing circuit control of social behavior

by  /  20 July 2021

When probing the circuits underlying social behavior in animal models of autism, researchers should consider potentially confounding variables, use multiple behavioral assays and report results in a descriptive and unbiased manner.

Blocking key pathway reverses brain, behavior changes in autism mouse model

by  /  19 July 2021

Neurons in mice with an autism-linked mutation sprout extraneous protrusions, an overgrowth accompanied by above-average motor learning. Inhibiting a cell signaling pathway reverses the effect.

Autism-linked mutation may blur brain’s boundary between self, others

by  /  15 July 2021

A mutation in the autism-linked gene SHANK3 changes how neurons encode information about social agency in mice.

Huda Zoghbi: Taking genetic inquiry to the next level

by  /  25 June 2021

Over the course of a career spanning more than three decades, Huda Zoghbi has won almost every major biology and neuroscience research award that exists. More than 20 years since she discovered the gene behind Rett syndrome, she remains laser focused on unlocking the condition’s secrets and finding effective treatments.

Autism-linked mutation may disrupt brain cell migration

by  /  23 June 2021

Mutations in CUL3, a leading autism gene, may disrupt the movements of neurons during development; correcting this misdirection could lead to an autism therapy.

Neural network captures noisy neurons in autism mouse model

by  /  18 June 2021

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.

Wireless optogenetic devices sync neurons among mice

by  /  17 June 2021

Researchers say they can synchronize two new devices and control neurons across 256 freely moving animals at once to study social behaviors.
