Abstract
PURPOSE OF REVIEW: Genetic studies in focal cortical dysplasia type II (FCD II) provided ample evidence for somatic mutations in genes associated with the mammalian target of rapamycin (mTOR) pathway. Interestingly, the mTOR pathway can also be activated by the E6 oncogene of human papilloma viruses, and available data in FCD II remain controversial. We review and discuss the contradicting etiologies. RECENT FINDINGS: The neuroembryologic basis of cortical development and timing of a somatic mutation occurring in proliferating neuroblasts can mechanistically link mTORopathies. When a somatic mutation occurs in proliferating neuroblasts at an early stage of their anticipated total number of 33 mitotic cell cycles, large hemispheric lesions will develop from their affected progeny. Somatic mutations occurring at later periods of neuroblast expansion will result in circumscribed and small FCD II. Recently published data did not support evidence for viral infection in FCD II. SUMMARY: Genetic and histopathological data rather than viral infection classify FCD II into the spectrum of mTORopathies. Size and extent of the resulting cerebral lesion can be well explained by timing of somatic mutations during cortical development.

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
