This review asks good questions and summarises well our lack of progress in answering them. The fundamental problem is the failure to conceptualise what a biologically plausible alternative to SLAM might look like.

The solution is likely to involve abandoning 3D coordinate frames and transformations. Instead, egocentric and allocentric tasks can be solved in a space of images or sensory states. This is what is done in reinforcement learning, which is probably a better model for biology than SLAM.
