Emotions are core to the human experience 😆😮🙂😊☹️😠😳😑. But how do they arise? Our brain-wide ⚡recordings in humans and mice reveal some answers @ScienceMagazine. A big team effort and debut paper from @Stanford's new Human Neural Circuitry program.

Thank you @StanfordMed for the detailed reporting on our work. And great title too! How we used an opthalmologist's tool to study the neural mechanisms of emotion.

Humans and mice share persistent brain-activity patterns in response to adverse sensory experience, Stanford scientists find, opening a window to our emotions and, perhaps, neuropsychiatric disorders.

Thank you @NPR @NPRHealth @nprscience for a beautiful piece about our work studying the neural basis of emotion. Your creativity in applying the piano analogy was 🎯 .

A study offers a glimpse of how the brain turns experience into emotion. In mice and humans, puffs of air to the eye caused persistent changes in brain activity, suggesting an emotional response.

It was amazing working on this with Ethan Richman, @liutony66 @KarlDeisseroth @CRodriguezMDPhD @VivekBuchMD, Paul Nuyujukian, @SamVesuna @chibyanada and many others. And we are very grateful for the incredible contributions of the participants who volunteered to be in the study.

We hypothesize that aspects of the etiology and treatment of certain neuropsychiatric disorders may be governed by alteration of such persistence-related phenomena.

By analogy to a piano's sustain pedal, emotional responses to sensory stimuli require the brain's "sustain pedal" to be activated, allowing signals to persist and accumulate.

One high level takeaway is that emergence of emotional responses in mammals seems to rely on the brain's capacity to sustain persistent activity dynamics. By pharmacologically disrupting this ability of the brain, we blunt emotional responses in both humans and mice.

Very excited about Ethan Richman’s study that provides deep insight into competition between homeostatic needs! The work has it all — a new behavioral assay, brain-wide Neuropixels + optogenetics, and a new framework for understanding brain state dynamics.
Excited to see Ethan Richman's tour de force study of homeostatic drive competition come out! Brain-wide Neuropixels + exciting new approaches for modeling internal states. With Liqun Luo and .@KarlDeisseroth.
