🚨New spotlight paper at Neurips 2025🚨
We show that in sign-diverse networks, inherent non-gradient “curl” terms arise, and can, depending on network architecture, destabilize gradient-descent solutions or paradoxically accelerate learning beyond pure gradient flow.

Curl Descent: Non-Gradient Learning Dynamics with Sign-Diverse Plasticity
Gradient-based algorithms are a cornerstone of artificial neural network training, yet it remains unclear whether biological neural networks use similar gradient-based strategies during learning. Expe...

In the past year and a half, we have been intensively protesting and fighting the Israeli government in an attempt to stop the war, secure the release of all hostages, and prevent the ongoing humanitarian crisis. Until now, our protests have primarily been focused internally.

Cerebellar output shapes cortical preparatory activity during motor adaptation - Nature Communications
Functional role of the cerebellum in motor adaptation is not fully understood. The authors show that cerebellar signals act as low-dimensional feedback which constrains the structure of the preparator...

Neural mechanisms of flexible perceptual inference
What seems obvious in one context can take on an entirely different meaning if that context shifts. While context-dependent inference has been widely studied, a fundamental question remains: how does ...
