Divisive Normalization Shapes Low-Rank Slow Manifolds for Continuous Working Memory
Zhaotian Gu, Jie Su, Weiwei Wang +3
The ability to robustly maintain and update continuous variables is a hallmark of working memory. While classical continuous attractor networks suffer from severe fine-tuning fragi…
Self-organized MT Direction Maps Emerge from Spatiotemporal Contrastive Optimization
Zhaotian Gu, Molan Li, Jie Su +3
The spatial and functional organization of the primate visual cortex is a fundamental problem in neuroscience. While recent computational frameworks like the Topographic Deep Artif…
A Unified Cortical Circuit Model with Divisive Normalization and Self-Excitation for Robust Representation and Memory Maintenance
Jie Su, Weiwei Wang, Zhaotian Gu +2
Robust information representation and its persistent maintenance are fundamental for higher cognitive functions. Existing models employ distinct neural mechanisms to separately add…
