To refine the mechanisms of simulated goal-directed activity among epilepsy patients in its relationship with clinical characteristics of the disease.</p> <p><bold>Materials and methods.</bold> A total of 72 virtually healthy persons and 163 epilepsy patients were examined. Seizure frequency, the levels of cognitive and emotional impairments, and the number of administered anticonvulsants were assessed. Electroencephalograms, parameters of visual and auditory evoked potentials, the cognitive evoked P300 potential, parameters of the motor systems, and autonomous maintenance of activity were recorded. Division into groups was performed by clustering analysis using the results of the Schulte–Gorbov test.</p> <p><bold>Results.</bold> The high- (99 patients) and low-effectiveness (64 patients) groups of epilepsy patients were revealed. The low-effectiveness group of patients was characterized by predominantly symptomatic forms of the diseases. High cross-correlation values, reduced frequencies of EEG alpha oscillations, reduction in the amplitude of the components of visual evoked potentials and the P300 potential, an increase in N2 and P3 peak latency in the low-effectiveness group of epilepsy patients were determined. Increased amplitude of the wave of conditionally negative deviation, slower latency of sensorimotor responses, reduced variability of heart rate, and increased respiratory rate group of patients were observed in this group of patients.</p> <p><bold>Conclusions.</bold> The inadequate performance in epilepsy patients is associated with the reduced activity of specific afferent associative subsystems and mechanisms of motor-based maintenance of performance, as well as with excessive activity of stress-inducing mechanisms, which increases the physiological costs and reduces the effectiveness of simulated activity.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение. </bold>Вариантом интегративного подхода в изучении механизмов эпилепсии является исследование системной организации целенаправленного поведения и анализ физиологических механизмов, обеспечивающих результативную деятельность пациентов с данным заболеванием.</p> <p><bold>Цель исследования</bold> – уточнение механизмов моделируемой целенаправленной деятельности у больных эпилепсией в связи с клиническими характеристиками заболевания.</p> <p><bold>Материалы и методы.</bold> Обследовано 72 практически здоровых человека и 163 больных эпилепсией. Проводилась оценка частоты приступов, уровня когнитивных, эмоциональных нарушений, числа принимаемых антиконвульсантов. Осуществлялась регистрация электроэнцефалограмм, показателей зрительных и слуховых вызванных потенциалов, когнитивного вызванного потенциала Р300, характеристик моторных систем и вегетативного обеспечения деятельности. Разделение на группы осуществлялось методом кластерного анализа по показателям выполнения теста Шульте-Горбова.</p> <p><bold>Результаты.</bold> Выделена результативная (99 пациентов) и низко результативная (64 пациента) группы больных эпилепсией. Низко результативная группа пациентов характеризовалась преобладанием симптоматических форм заболевания. Установлены большие значения кросскорреляции и снижение частоты альфа-колебаний электроэнцефалограмм, уменьшение амплитуды компонентов зрительных вызванных потенциалов и потенциала Р300, увеличение латентности пиков N2 и P3 потенциала Р300 в низко результативной группе больных эпилепсией. В данной группе пациентов определяется снижение амплитуды волны условно-негативного отклонения, замедление времени сенсо-моторных реакций, уменьшение вариабельности сердечного ритма, увеличение легочной вентиляции.</p> <p><bold>Заключение.</bold> Недостаточная результативность деятельности у больных эпилепсией обусловлена сниженной активностью специфических афферентных, ассоциативных субсистем и механизмов моторного обеспечения деятельности, а также избыточной активностью стресс-реализующих механизмов, что увеличивает физиологическую стоимость и уменьшает эффективность моделируемой деятельности.</p></trans-abstract><kwd-group xml:lang="en"><kwd>epilepsy</kwd><kwd>performance efficiency</kwd><kwd>physiological mechanisms</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эпилепсия</kwd><kwd>эффективность деятельности</kwd><kwd>физиологические механизмы</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Anokhin P.K.
