Self-organized MT Direction Maps Emerge from Spatiotemporal Contrastive Optimization

ArXi:2605.11718v1 Announce Type: cross The spatial and functional organization of the primate visual cortex is a fundamental problem in neuroscience. While recent computational frameworks like the Topographic Deep Artificial Neural Network (TDANN) have successfully modeled spatial organization in the ventral stream, the computational origins of the dorsal stream's distinct topographies, such as direction-selective maps in the middle temporal (MT) area, remain largely unresolved.
