Summary

Story summary

Stanford researchers pinpointed the reticular thalamic nucleus as a key brain region affecting autism-like behaviors in mice.
Overactive neurons here disrupt sensory processing, causing symptoms like social avoidance and hyperactivity.
Treatment with Z944, a calcium channel blocker, enhanced social interaction and reduced grooming behaviors.
DREADDs also improved behaviors by controlling neuron activity.
The findings indicate autism symptoms may stem from deeper brain regions, warranting further research and human trials.
