We're hiring! Our lab at Brown University has 2 immediate openings for full-time Research Assistants! Assist in ongoing funded projects on the neuroscience of cognitive control using fMRI, EEG, and behavior. If you're interested contact us at: [email protected]

Some professional news: I'm thrilled to be joining Brown Cog, Ling, & Psych Sciences & Nelson Center E-Ship this summer as an Assistant Professor of Cognitive, Linguistic, & Psychological Sciences and Entrepreneurship! Try to say that five times fast. (1/6)

Therefore, at least in highly trained subjects, lPFC learned task-tailored representations that recapitulated the structure of the task, showing that lPFC representations are shaped by representation learning.

On the other hand, in the flat task, a global axis encoded the response-relevant, XOR categories abstractly. Category-specific local geometries were high-dimensional, retaining stimulus information that was not strictly required for readout.

In the hierarchy task, the global axis abstractly encoded higher-level context, while low-dimensional, context-specific local geometries compressed context-irrelevant information & abstractly encoded context-relevant response-relevant category.

Delighted to see this important work on the representation of task structure out there. We learned a lot from this project.

This was a marathon but the finish line was well worth it! Very happy for Apoorva Bhandari and haley keglovits to have reached this point.

Check out Defne Buyukyazgan's poster happening now on how lateral PFC representational geometry shapes control function #SfN2023 David Badre

Presentation PSTR434.07 / UU4

#SfN2023 Society for Neuroscience (SfN) I will present his poster “Error Monitoring is Modulated by Conjunctive Representations of Committed and Uncommitted Actions' (PSTR434.13: UU10, 1-5 PM on 11/14).

This is a really terrific review by Tobias. Integrates a range of findings within a clear framework. This is a highly recommended read.

🚨New preprint alert!🚨

In 1st study from my postdoc, Stephanie Jones and I (in collab with Jan Wessel, janw.bsky.social ) used Human Neocortical Neurosolver to model thalamocortical mechanisms of the human frontocentral ERP during stopping.

We offer novel, testable predictions about those mechanisms. 🧵👇 (1/)

I wrote about 'Action Stopping' for the 2nd Ed. of the Encyclopedia of the Human Brain. I know book chapters can be of low interest to readers (and writers), but I tried to make it a worthwhile & somewhat comprehensive intro for new trainees. Find it here: osf.io/preprints/psya…
