Abstract

fetched live from OpenAlex

Habituation and spontaneous recovery from habituation to tap were studied across development in C. elegans. Unlike adult worms, larval worms do not consistently swim backwards to tap, but reverse half of the time and accelerate forward half of the time. In adult worms, the tap response is produced by the integration of two competing circuits: The head touch circuit, mediated by ALM and AVM sensory neurons, produces backward movement (reversals); the tail touch circuit, mediated by PLM neurons, produces forward movement (accelerations). Because the response type changes over development, habituation of each of the subcircuits was studied separately. Habituation of the head touch circuit was studied by laser ablating PLM, and habituation of the tail circuit was studied by ablating ALM. Worms were tested at six stages of development at either 10- or 60-s interstimulus intervals. All stages of development showed normal habituation and spontaneous recovery at both interstimulus intervals.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
