Transcranial ultrasound stimulation can reach deep brain regions such as the amygdala, modulate ongoing task-related activity, and bias emotional responses. Nice to see this impressive brainstim-MRI study from @mkflugge.bsky.social lab come together and glad to have been involved.

Public communication alters private confidence Andreassen et al. demonstrate that confidence exhibited in public affects our private assessment of confidence.

How does uncertainty transmit from one head to another? Our new paper out today in @currentbiology.bsky.social reveals how public communication alters private confidence.

We used computational modeling to predict, trial-by-trial, the exact moments when learners updated a memory or created a new one.

We then asked what brain regions tracked the shift between these predicted operations.

What happens when we can't use recursive belief to compete? We can use anomaly detection instead!
