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
- Place Cellsanalogous_toHippocampal neurons with spatially-specific firing; TEM-t memory neurons resemble these and remap randomly between environments.
- Large Associative Memory Problem in Neurobiology and Machine Learning (Krotov & Hopfield, 2020)introducesPaper proposing neurally plausible instantiation of Hopfield/transformer with feature neurons and memory neurons; used to derive place cell interpretation.
