At #SfN24? Come check out my poster F3 on how population activity in V1 informs perception decision and confidence

Huge thanks to our PI Robbe Goris and the members of the Goris lab who supported this work, @CMZiemba @zoebsinger @yoon_bai Quiana Jeffs and @9Gaby_Reyes

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.

[Goris Lab @GorisLab]

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.

[Goris Lab @GorisLab]

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.

[Goris Lab @GorisLab]

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.

New preprint from @ThomasALanglois and @julie_charlton_ ! https://t.co/LExXWComj3

We asked how prior expectations are combined with sensory signals to form a perceptual decision in macaque PFC.

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...

[Goris Lab @GorisLab]

Check out the exciting work of @MiguelVivarLazo and @chris_fetsch who examine the temporal evolution of choice and confidence signals in LIP using a similar explicit confidence reporting task https://t.co/thZcY70ZU4

New from the lab, work by @zoebsinger and @CMZiemba. Here we investigated how population activity in early sensory cortex informs perceptual choices as well as perceptual confidence. https://t.co/ME5KJujT34

[Goris Lab @GorisLab]

This paradigm holds great utility for addressing questions far beyond those we tackled.

Response sub-additivity and variability quenching in visual cortex — a Perspective by Robbe L. T. Goris, Ruben Coen-Cagli, Kenneth D. Miller, Nicholas J. Priebe & Máté Lengyel

[Máté Lengyel @lengyel_m]

Sub-additivity (aka. response normalization) and variability quenching often go hand-in-hand in cortex. Why? We provide some potential answers: https://t.co/0eaneVC20p -- a review with @GorisLab @CoenCagli_Lab @kendmil and Nick Priebe.

[Goris Lab @GorisLab]

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.

[Goris Lab @GorisLab]

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

[Zoe Boundy-Singer @zoebsinger]

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.

[Goris Lab @GorisLab]

New out from the lab, a project headed by former graduate student Dr. @julie_charlton_ :
