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 ...

What is the representation underlying cognition? Formal models rely on multidimensional scaling of similarity judgments to derive the representation. In this preprint with @mdlbayes.bsky.social, we take an alternative approach; we build Bayesian generative models for three cognitive tasks. /1
Similarity judgments and visual working memory do not share the same cognitive representation: https://osf.io/fm9vz

How does our brain excel at complex object recognition, yet get fooled by simple illusory contours? What unifying principle governs all Gestalt laws of perceptual organization?

We may have an answer: integration of learned priors through feedback. New paper with @kenmiller.bsky.social! 🧵

The final bit of work from my PhD just got published at JOV! We looked at similarity judgements made for naturalistic image patches, and whether these are predicted by simple image statistics… (spoiler: yep!)

Excited to share my PhD paper! In it, we use targeted 2-photon optogenetic stimulation to determine how V1 activity is read-out in a detection task. We found that network influence, not visual coding properties, predicted the impact of ensembles on behavior - contradicting our expectations (1/5).
