Place Cells

Hippocampal neurons with spatially-specific firing; TEM-t memory neurons resemble these and remap randomly between environments.

Neighborhood — ranked by edge-count

framework

Feature Neurons and Memory Neurons Architecture
analogous_to
Biologically plausible two-pool architecture from Krotov & Hopfield (2020) splitting self-attention into feature and memory neuron populations; used to interpret TEM-t place cells.

concept

Outer Product Conjunctive Representations
analogous_to
TEM's method of binding location g and sensory x representations by computing their outer product; corresponds to place cells.
Hippocampus
associated_with
Brain region corresponding to the memory/conjunction component in TEM; memory neurons resemble place cells.

cosine ≥ 0.65 · no typed edge

Entities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.

Biological units that are considered unconventional media for problem-solving in diverse intelligence.
Place Cell Remappingconcept0.823
Phenomenon where place cells change their spatial tuning across environments; TEM-t memory neurons exhibit this property.
Grid Cellsconcept0.793
Spatially periodic firing neurons in medial entorhinal cortex; TEM-t learns representations resembling these.
Band Cellsconcept0.767
Spatially periodic band-like firing neurons described by Krupic et al.; also recapitulated by TEM-t position encodings.
