Abstract

fetched live from OpenAlex

Previous research has shown that seizures kindled in the corpus callosum result in a persistent enhancement of the callosal-neocortical evoked response but only a transient reduction in layer III pyramidal cell morphology. To date, there are no reports on the direct effects of repeated seizures on dendritic morphology in layer V, the pyramidal layer thought to mediate the kindling-induced enhanced evoked response. This experiment examined the effect of repeated seizures elicited from the corpus callosum, at the level of the frontal neocortex, on the morphology of sensorimotor frontal (Fr1) and occipital (OC1) neocortical layer V, as well as striatal and neuronal dendrites, in male rats. After 25 days of electrically elicited seizures or handling control, rats were sacrificed either 2 days or 3 weeks following the last seizure and processed for Golgi-Cox staining. Analysis of the impregnated pyramidal cell dendrites indicated a significant increase in the amount of dendritic length and branching in rats 2 days, but a decrease 3 weeks, following the last seizure. There was no effect at the distant occipital site. The differential effect between layer V pyramidal neurons and layer III pyramidal neurons suggests that these areas play different roles in the expression of seizures and the adaptation of the brain to the persistent effect of kindling.

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.
