Simulations of bounded drift diffusion showed that these observations were consistent with a prior-induced offset and drift rate, revealing a mechanism by which prefrontal circuits can implement Bayesian-like inference.

These findings are consistent with an approximate hierarchical inference process as proposed by Lange et al. (2021) @wrongu from @haefnerlab in which initial prior beliefs become entrenched through confirmation bias.

We found that prior expectations impact the DV′s trajectory both before *and* during stimulus presentation such that DV trajectories with a smaller dynamic range result in more biased and less sensitive perceptual decisions.

New preprint from @ThomasALanglois and @julie_charlton_ ! tinyurl.com/kfckzx8j We asked how prior expectations are combined with sensory signals to form a perceptual decision in macaque PFC.

Importantly, we leveraged a task design that produced a bias in monkeys’ perceptual judgements, but not their motor reports. This allowed us to isolate the perceptual component of the decision variable.

Happy to share a new preprint by the brilliant and indefatigable @MiguelVivarLazo. The first of several stories we want to tell with this rich dataset, which features joint measurements of choice, reaction time, and confidence along with ensemble recordings from LIP...

Sub-additivity (aka. response normalization) and variability quenching often go hand-in-hand in cortex. Why? We provide some potential answers: rdcu.be/dy1q5 -- a review with @GorisLab @CoenCagli_Lab @kendmil and Nick Priebe.

The Goris lab has two posters at #SfN23 . Tomorrow morning come learn about metacognitive learning. At Tuesday's afternoon session learn about how neural population dynamics predict the use of prior information in perceptual decision making.

This afternoon, Ruben Coen-Cagli and Robbe Goris are co-hosing a mini-symposium: Suppression and Variability in Visual Cortex highlighting theoretical and empirical work which is revealing the link between these two concepts. Come checkout our great line-up of speakers! #SfN23

At #SfN23? This afternoon I'm excited to share our work on the representation of uncertainty in visual cortex in the minisymposium on suppression and variability in visual cortex.
