How to implement 6DoF state estimation on 3D manifold based on neural dynamics?

State estimation in high dimensional space is a big challenge problem. Commonly, we use Lie group to implement 6DoF state estimation in 3D space. However, how does the brain implement path integration in 3D space based on neural dynamics?

Low …
