Abstract

fetched live from OpenAlex

ЦЕЛЬ ИССЛЕДОВАНИЯ Выполнена оценка нарушений когнитивных функций и исследование организации биоэлектрической активности мозга в цикле сон—бодрствование у пациентов с опухолями лобной доли. МАТЕРИАЛ И МЕТОДЫ Обследованы 20 пациентов обоих полов в возрасте 48,6±6,4 года, а также 10 здоровых (контроль). В 1-ю группу были включены пациенты без неврологических нарушений с опухолями, средний объем которых составил 8,9±5,1 см3, во 2-ю — пациенты с признаками лобной дисфункции, средний объем новообразований у которых составил 40,7±2,1 см3. Для оценки нарушений когнитивных функций была использована батарея тестов. Регистрировалась ЭЭГ бодрствования и ночного сна. РЕЗУЛЬТАТЫ Установлено, что ухудшение когнитивных функций у пациентов с опухолями лобной доли сопровождалось ростом мощности дельта- и тета-диапазонов и ареактивностью коры в бодрствовании, увеличением мощности в диапазоне частот дельта-, тета-, альфа-ритмов, уменьшением активаций в фазе быстрого сна. ЗАКЛЮЧЕНИЕ Полученные данные могут быть полезны в поиске маркеров ранних признаков ухудшения когнитивных функций у пациентов с опухолями лобной доли с целью своевременного осуществления коррекции функционального состояния пациентов.

Not 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.
