Novel place cell metric (largest connected component firing mass ratio) successfully distinguishes TEM-t memory neurons (place cells) from RNN neurons (grid cells)

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

• Novel Place Cell Metric (Connected Component Firing Mass Ratio)method0.866
  Novel evaluation metric introduced in this paper to quantify how place-like a neuron's firing rate map is, based on largest connected component.
• TEM-t memory neurons show spatially-tuned firing resembling hippocampal place cells in each environmentfinding0.815
  Empirical result demonstrating that the sparse softmax activation of memory neurons produces place-cell-like spatial tuning.
• would place-like representations emerge in memory neurons for activation functions other than softmax?question0.769
  Open empirical question left for future work about robustness of place cell emergence.
• Cells exhibit generalization in physiological space, recognizing novel stressors as members of familiar classes to deploy transcriptional solutions.hypothesis0.763
  Predicts that cells can categorize perturbations and mount appropriate, not just hardwired, responses.
• TEM-t instantiates hippocampal indexing theory by using memory neurons to bind cortical representations across brain regionsclaim0.760
  Theoretical claim linking the TEM-t architecture to the Teyler-Rudy hippocampal indexing theory.
• Neural Representations of Location Composed of Spatially Periodic Bands (Krupic et al., 2012)concept0.759
  Discovery of band cells; TEM-t also recapitulates these representations.
• TEM-t with linear activations learns grid-cell-like position encoding representations in 2D spatial environmentsfinding0.758
  Empirical result showing TEM-t recapitulates entorhinal grid cell representations with linear post-transition activation.
• Cells and cellular networks have problem-solving capacities that allow them to navigate entirely novel stressors (e.g., barium) without prior selection, implying a general competency beyond hardwired responses.claim0.753
  Derived from the planarian barium adaptation finding.
