The award covers travel, hotel, food and registration. It is a great opportunity to learn more about computational neuroscience, particularly for students considering graduate study. We especially encourage applications from traditionally under-represented/under-served groups.

The thing about going after universities is that you are going to find people who are experts in what you're doing

Rarely categorical, always high-dimensional: how the neural code changes along the cortical hierarchy A long-standing debate in neuroscience concerns whether individual neurons are organized into functionally distinct populations that encode information differently ("categorical" representations) and the implications for neural computation. Here, we systematically analyzed how cortical neurons encode cognitive, sensory, and movement variables across 43 cortical regions during a complex task (14,000+ units from the International Brain Laboratory public Brainwide Map data set) and studied how these properties change across the sensory-cognitive cortical hierarchy. We found that the structure of the neural code was scale-dependent: on a whole-cortex scale, neural selectivity was categorical and organized across regions in a way that reflected their anatomical connectivity. However, within individual regions, categorical representations were rare and limited to primary sensory areas. Remarkably, the degree of categorical clustering of neural selectivity was inversely correlated to the dime

How do interneurons reshape neural responses? I'm excited to present work with @eerosim.bsky.social at #NeurIPS2024 that proposes a nonlinear recurrent circuit model motivated by efficient coding theory.

I will soon delete all my twitter posts, so in the next few days I will be recycling some of my most liked tweets, in random order. The first one had to be a shitpost, of course

Since we are in full migration season from the birdsite, I made this to help ppl from the Zuckerman Institute find each other / anybody interested in this amazing community to single-click follow a bunch of 🧠s working on 🧠s. Dm/comment for additions, I just started with the first few I could find
