@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...

Do you like RSA analysis, M/EEG and Bayes? Then you'll love Variational RSA for M/EEG, by recently completed PhD student @alexlepauvre.bsky.social from Lucia Melloni's group. It's a method and SPM toolbox for multivariate analysis of M/EEG data. arxiv.org/pdf/2511.01784 . 🧵 [1/4]

Now out in #ScienceAdvances: @baiweiliu.bsky.social and I ask how internal (goal) and external (sensory) selection are coordinated during visual search. The key insight: internal and external selection are not inherently serial, but may develop in parallel in the human brain: doi.org/10.1126/scia...
Concurrent selection of internal goals and external sensations during visual search
Internal and external selection processes can codevelop in time to yield efficient search behavior.

I had a run in with ICE snatching a man out of his car while walking my children to school this morning in NW DC

I asked a neighbor to continue walking my kids to school and I turned back to document and confront the ICE agents.

I am in contact with @dcmigrantmutualaid.org with the full video.

Interested in how we make preference-driven decisions, and how this is implemented in the brain?

We report that neural correlates of evidence accumulation (CPP, Mu/Beta) are also observed during value-based decisions.

Tracing the neural trajectories of evidence accumulation and motor preparation processes during voluntary decisions
Voluntary decisions have previously been described by where they arise in the brain and how actions corresponding to one's choice are prepared. However, the processes by which these internally guided ...
