Abstract
Induction of immediate early gene (IEG) expression is believed to constitute one of the earliest steps in plasticity and long-term modification of neuronal properties. Although behavioral evidence of neuronal plasticity at the sublesional level after spinal cord injury exists, spatiotemporal changes of IEGs in spinal segments located caudally to such an injury have never been examined. Here, the authors studied spatiotemporal changes of c-fos, nor-1, nur77, nurr1, and retinoid x receptor (rxr) messenger RNA expression in the lumbar segments L1-L2 after low-thoracic spinal transection (Tx). C-fos expression generally increased in the dorsal horn with significant levels reached at 3 days and 14 days post-Tx. Basal nor-1 transcript levels decreased in the intermediate zone and dorsal horn areas at 7 days. Nur77 levels were nonsignificantly depressed throughout that period of time, whereas nurr1 and rxr transcripts were not detected before or after Tx. In conclusion, the results provide evidence of distinct roles for c-fos and nor-1 in reorganization and plasticity of neuronal networks typically involved in sensorimotor integration and locomotor control.

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
