1/11 Happy to share our TICS paper on using the flexibility of one of the most basic cognitive functions, perception, to understand one of the most complex cognitive dysfunctions, psychiatric conditions (also my first formal work in computational psychiatry 🎉)

NEW PAPER. Why do larger networks train better?

Differences stemmed from the way researchers defined concepts, to the algorithms they used to analyze the data, to the parameters they employed when implementing the algorithms, note @mattiachini.bsky.social and Gaelle Chapuis. #neuroskyence

Question to any attention researchers following this account:
Do you know of ANY theory/model of visual attention that defines or explains what is "attentional selection"?
Anything that comes to mind will do.
Extra points if they're detailing a mechanism that underlies it.

Once upon a time Sage Boettcher was my fresh-out-of-college Research Assistant. Now she is faculty at Oxford. I am delighted to still be invited to collaborate with her.

Online Now: Perceptual multistability: a multifaceted window into brain dysfunctions
Disagreement in neuroscience runs deeper than most researchers suspect—even in electrophysiology, a field that prides itself on hard data.

🧵 How does the human brain turn experiences into memories?
During my four years of PhD at Oxford, I investigated this question through a collaboration between Oxford, Toulouse, and Paris, recording directly from the human brain during a relational memory task.

Perceptual multistability, observed across species and sensory modalities, offers valuable insights into numerous cognitive functions and dysfunctions. For instance, differences in temporal dynamics and information integration during percept formation often distinguish clinical from nonclinical populations. Computational psychiatry can elucidate these variations through two primary approaches: (i) Bayesian modeling, which treats perception as an unconscious inference, and (ii) an active, information-seeking perspective (e.g., reinforcement learning), which frames perceptual switches as internal actions. Our synthesis aims to leverage multistability to bridge these computational psychiatry subfields, linking human and animal studies as well as connecting behavior to underlying neural mechanisms. Perceptual multistability emerges as a promising noninvasive tool for clinical applications, facilitating translational research and enhancing our mechanistic understanding of cognitive processes and their impairments.
