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.

I'm really looking forward to talking about my PhD work tomorrow (Tues.) in which we tested the intentional hypothesis in PFC using population ephys and a flexible decision making task. MOVED to 2:45 pm in SDCC 23 #sfn22

Now published!

This research from Boundy-Singer et al. models the relationship between people's confidence and the accuracy of their decisions. The authors argue that their framework describes mechanisms behind the sense of confidence better than previous models. buff.ly/3NFUnoe

Moments of transition often induce uncertainty about the underlying context (does the 1st ⚡️ really announce 🌧?) In a new preprint, we* asked: how do people use context-specific prior knowledge when there’s uncertainty over both stimulus & context? tinyurl.com/4jn4bcmt 1/13

How do we know which decisions are more likely to be correct? What limits this metacognitive ability? In our new preprint we propose a process model, CASANDRE, (Confidence AS A Noisy Decision Reliability Estimate) of decision confidence. More below 1/x biorxiv.org/content/10.1101/…

Confidence as a noisy decision reliability estimate

Decisions vary in difficulty. Humans know this and typically report more confidence in easy than in difficult decisions. However, confidence reports do not perfectly track decision accuracy, but also...

How does the brain make predictions about its environment? We found primary visual cortex to straighten the temporal trajectories of natural videos, facilitating their extrapolation. nature.com/articles/s41467-0…

How does the brain keep track of its uncertainty? We found neural gain variability to represent stimulus uncertainty across the visual hierarchy, and explain these findings with a stochastic variant of divisive normalization: nature.com/articles/s41467-0…
