I will be recruiting 🌟PhD students🌟 for my newish lab! If you're interested in learning & memory mechanisms applied to individual, interactive & collective behavior using computational modeling, real-world experiments and fMRI, email me! RTs much appreciated 🙏 rouhanilab.com

AI-guided digital intervention with physiological monitoring reduces intrusive memories after experimental trauma Trauma prevalence is vast globally. Evidence-based digital treatments can help, but most require human guidance. Human guides provide tailored instructions and responsiveness to internal cognitive sta...

I'm excited to share a new preprint! We built a digital, scalable intervention to reduce intrusive memories, combining an AI chatbot with LLM scoring of human-AI conversations and pupillometry predictors of effort and intervention success. I hope you enjoy! arxiv.org/abs/2507.01081

Noninvasive precision modulation of high-level neural population activity via natural vision perturbations Precise control of neural activity -- modulating target neurons deep in the brain while leaving nearby neurons unaffected -- is an outstanding challenge in neuroscience, generally approached using inv...

this is wild and amazing! selective modulation of neurons in the ventral visual stream noninvasively, just by changing the visual input.

i've recently been saying that the senses are a powerful, overlooked BMI... the OG BMI designed by nature 😉 think of the possibilities!
