Our new paper on large scale holographic read-write experiments observing and controlling thousands of neurons in mouse visual cortex reveals a new functional cell-type that detects even moderate levels of excess activity (just 50 extra neurons firing) then inhibits top down cortical inputs.
This cell type is a subclass of somatostatin neurons, whose dysfunction is implicated in schizophrenia.
This suggests an intriguing hypothesis for the origins hallucinations in schizophrenia: the breakdown of this highly sensitive cortical gate allows top down inputs to enter visual cortex that should not, creating hallucinations.
This work was expertly lead by @ADrinnenberg w/ @allanraventos and @Alex_Attinger on data analysis and theory. Another fun collab w/ @KarlDeisseroth!

Amazing collaboration with @AllenInstitute team—@HongkuiZeng, @BosiljkaTasic, Tanya L. Daigle, La'Akea Siverts—to develop new transgenics for all-optical neuroscience.
And deeply grateful to @KarlDeisseroth for his support and mentorship. 🙏

✨New preprint✨ Ever dreamed of combining brain-wide fUS imaging, two-photon imaging, ephys, and optogenetics in mice during your favorite head-fixed task? Want to also capture their facial expressions? We present the COMBO window to facilitate all these techniques!
We’re excited to extend noninvasive optogenetics beyond the brain to address a nearly 150-year-old question in a new study out today @Nature:
