Whether hippocampal spatial coding principles also provide a universal metric for the organization of non-spatial information?

The latest investigation by Theves et al. 2019  revealed the hippocampus encodes distances in multidimensional feature space.

• The hippocampus encodes distances in multidimensional feature space
• Converging evidence from multivoxel pattern and fMRI adaptation analyses
• Results suggest …
