Made an AI-curated primate ephys literature database covering ~10000 papers with recording brain regions and target functions. Maybe useful for something.

New review with Cheng Xue at U Chicago @cxue.bsky.social in Trends [email protected]! We discuss the neural geometry of task-dependent computation: disentangled encoding, RNN modeling, switch cost, etc.

Excited to share our new review in Trends in Neuroscience with Gouki Okazawa @gouki-okazawa.bsky.social :
"The 'neat' and 'messy' in task-dependent neural geometry and computation"
where we reviewed what we know about the 'task-manager' in the brain.

The ‘neat’ and ‘messy’ in task-dependent neural geometry and computation
by Cheng Xue @cxue.bsky.social & Gouki Okazawa @gouki-okazawa.bsky.social

To solve diverse real-world tasks, the brain must flexibly switch between task rules
and adjust computations. Recent advances in analyzing neural data and modeling neural
networks have revealed their ...
Final paper of my PhD 🤗

There is growing interest in how cognitive control may improve value-based decision making.
However, we find that a recent paper overestimated the role of control in their task, leading to erroneous interpretations of dACC recordings.
The basal ganglia output is often framed as a motor gate: corticostriatal circuits select an action, then GPi/SNr-thalamus helps release it. In humans, we find this same pathway carries cognitive variables embedded in movement signals—and even produces learning-relevant signals after feedback. 1/10

In a new computational analysis of previous work, this study shows that a control-free mechanism better accounts for value-based decisions than an account that assumes top-down control invigorating th...
Perceptual decisions unfold over time, requiring neural circuits to evaluate sensory evidence, track elapsed time, and commit to an action. To investigate how these computations are distributed across...
Task rules critically shape how neural populations encode information and generalize across cognitive demands, yet the mechanisms linking rule structure, neural dynamics, and behavior remain poorly un...
I’m building a foundational reading list for our lab (systems & circuit neuroscience, compneuro, modeling, neuromodulators, population coding etc.).
I’d like to crowdsource recommendations.
Which review(s) would you consider mandatory reading for the next generation of researchers?
