New study out today in Nature Comms: www.nature.com/articles/s41..., in which we set out to test whether ultrasound could influence the reward-related learning computations of the nucleus accumbens, building on decades of work on dopaminergic prediction error and reinforcement learning. And it did.

@dotproduct.bsky.social's first first author paper is finally out in @sfnjournals.bsky.social! Her findings show that content-specific predictions fluctuate with alpha frequencies, suggesting a more specific role for alpha oscillations than we may have thought. With @jhaarsma.bsky.social. 🧠🟦 🧠🤖

Contents of visual predictions oscillate at alpha frequencies
Predictions of future events have a major impact on how we process sensory signals. However, it remains unclear how the brain keeps predictions online in anticipation of future inputs. Here, we combin...

Confronting the connectivity crisis in human M/EEG research
The cognitive neuroscience community using M/EEG has not converged on measures of task-related inter-regional brain connectivity that generalize across tasks and laboratories. We call for community-driven efforts to systematically test and validate connectivity metrics using shared datasets and protocols, aiming to establish robust, replicable frameworks for cognitive and clinical applications.

For TMS studies to be reproducible and for us to build on each other’s findings, we need to report what we actually did during the experiment. We've built and now are evaluating the TMS-RAT (Reporting Assessment Tool). Check out our website! - built by @thehandlab.bsky.social

Together, our results demonstrate that a key mechanism through which the brain distinguishes imagination from reality is by monitoring the activity of mid-level sensory cortex. We hope these findings lay the foundations for future research on a generalised reality monitoring system in the brain 13/N
