TEM's method of binding location g and sensory x representations by computing their outer product; corresponds to place cells.

- Tolman-Eichenbaum Machine (TEM)implementsNeuroscience model of hippocampal formation that the paper shows is mathematically equivalent to a transformer with recurrent position encodings.
- Hippocampal Indexing TheorysupportsTheory that hippocampus provides an index binding together cortical patterns across different brain regions; TEM-t is shown to instantiate this.

- Place Cellsanalogous_toHippocampal neurons with spatially-specific firing; TEM-t memory neurons resemble these and remap randomly between environments.
- Paper exploring two-type feature binding in dense associative memory; analogous to TEM-t binding g and x in memory neurons.
