framework:hippocampal-indexing-theoryHippocampal Indexing Theory
Theory that hippocampus provides an index binding together cortical patterns across different brain regions; TEM-t is shown to instantiate this.

Concepts (1)
concept
- TEM's method of binding location g and sensory x representations by computing their outer product; corresponds to place cells.
Claims (1)
claim
- Theoretical claim linking the TEM-t architecture to the Teyler-Rudy hippocampal indexing theory.
Frameworks (1)

- TEM-Transformer (TEM-t)implementsThe transformer version directly analogous to TEM, introduced in this paper, offering dramatic performance improvements.
