Stages of Memory in the Nematode Caenorhabditis Elegans
Bibliographic record
Abstract
Studies on the cellular basis of learning and memory have revealed several distinct phases of memory that can be distinguished by their time course. In addition to the traditional short-term and long-term memory distinction, several other phases of memory have been identified: forms of intermediate-term memory, at least two seperable forms of long-term memory, and possibly several forms of short-term memory. This article presents the contributions made by research on phases of memory for habituation in the nematode Caenorhabditis elegans. Through behavioral, neural circuit and genetic analyses of habituation, research using this simple organism has provided insights into different memory phases. Studying experience-dependent plasticity of this behavior has not only provided corroborating evidence for the existence of short-, intermediate-, and long-term forms of memory, as have been demonstrated in both Aplysia and Drosophila, but also has revealed the possible existence of multiple forms of short-term memory.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
