I argue that the brain navigates through image space rather than using a 3D coordinate-based reference frame.

Here is preprint corresponding to the talk I gave at #iNav2024: 'Navigating image space' doi.org/10.31234/osf.... No data, but some thoughts about the difference between Cartesian (grid-like) reference frames and an image-based frame for navigation.

A comprehensive review of VR and real world memory for object location (e.g. task: replace object in correct position). Some sex differences and better performance in real environments. There is no theoretical model here - that was not the goal. doi.org/10.1016/j.bb...

Excellent study of posterior parietal cortex (PPC) and hippocampal (HPC) cell responses as two macaques explore a virtual maze. www.nature.com/articles/s41...

Always thought provoking. Not a good model for biological 3D vision, in my view, but that is not Davison’s goal. Biologists need to know about working versions of (or feasible hypotheses for) the processes they are studying, and these systems really work.

What are the important questions about biological 3D vision and navigation that can be informed by recent advances in reinforcement learning?
