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.

Here is a roundup of news and research for the week of 26 June.
Memories from Diering’s life trace the rising star’s scientific path from raising lizards as a child and later exploring home brewing to heading a lab that investigates memory, sleep disturbances and early development in animals with autism-linked mutations.
Brain responses to visual stimuli are smaller and weaker in children with Phelan-McDermid syndrome, an autism-linked genetic condition, than in non-autistic children.
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.
Merging 3D clusters of neurons that mimic different brain regions models the atypical electrical activity seen in an autism-related condition.
The autism gene SHANK3 is crucial for the development and function of muscles and the motor neurons that control them.
Doctors often conflate autism and intellectual disability, and no wonder: The biological distinction between them is murky. Scientific progress depends on knowing where the conditions intersect — and part ways.
Mice missing an autism gene called SHANK3 tend to be hypersensitive to touch, which may stem from underactivity of neurons that normally dampen sensory responses.
After a decade of working with the Phelan-McDermid Syndrome Foundation, Geraldine Bliss has co-founded a new organization to develop therapies for the condition.
