Lasting Secondary Antiepileptogenesis Induced by Cingulate Kindling
Bibliographic record
Abstract
PURPOSE: To test the validity of a hypothesis that kindling-induced enduring kindling inhibition of the homotopic secondary site is not a primate species-specific effect but occurs also in feline species. METHODS: Five mature male cats were kindled at the anterior (AC) and posterior (PC) cingulate cortex followed by secondary-site kindling and primary-site retest. RESULTS: Kindling was characterized by a marked seizure-stage instability and a progressive afterdischarge threshold elevation in all the animals. A protracted nonconvulsive seizure stage was followed by convulsive evolution and rapid generalization. At the secondary site, positive transfer effect was absent, and kindling did not occur. Primary-site retest activated kindled seizure within three stimulations. Recurrent spontaneous seizures, identical to the primary-site kindled seizure, occurred in two AC-kindled animals. Subsequent to this, a markedly elevated afterdischarge threshold also was found at some distant cortical and subcortical sites, to which the afterdischarge propagated. Kindling of the amygdala ipsilateral to the kindled AC or PC was tardy, with no positive transfer effect. However, it was associated with afterdischage threshold reduction. CONCLUSIONS: Cingulate kindling-induced enduring kindling inhibition at a homotopic secondary site is not a primate species-specific effect and occurs also in feline species. It is not limited to a homotopic site and represents a lasting secondary antiepileptogenesis, presumably due to enhanced intrinsic inhibitory mechanism(s) available to the mammalian brain. A selective afterdischarge threshold elevation concurrently observed is suspected to be a feline species-specific effect.

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.
