Abstract
We investigated the role of the Caenorhabditis elegans CREB (cAMP response element binding protein) homologue, crh-1, in response to tap (nonlocalized mechanosensory stimulation) and tap habituation. Worms with a loss-of-function mutation in crh-1 performed smaller reversals in response to tap than did wild-type worms and did not show long-term memory for spaced training 24-hr posttraining; however, they did show short-term habituation to tap stimuli when stimuli were presented at both 10-s and 60-s interstimulus intervals, and showed 12-hr intermediate memory for spaced habituation training (intermediate-term memory). Expressing CRH-1 broadly throughout the nervous system and in a subset of interneurons of the tap withdrawal circuit, but not in the mechanosensory neurons, rescued the long-term memory defects observed in crh-1 mutants. Here we show for the first time that CREB is required for long-term habituation and show that the interneurons of the tap withdrawal response circuit are the locus of plasticity for long-term mechanosensory habituation in C. elegans.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
