  1. 16th world congress of psychophysiologySEPTEMBER 13-17 PISA, ITALY

  2. Invited lectures: Wolf Singer (Max plank Institute for Brain Research, Frankfurt, Germany) What binds us all together? Temporal coordination of neural responses in normal and pathological cognition Кодирование как частотой разрядов так и их синхронизацией (независимость) Когерентность как нейрональный коррелят сознания Место и частота

  3. Invited lectures: Leslie Prichep (Brain research laboratories, NY University School of Medicine) • The evolution of quantitative EEG and source localization: Toward optimization of treatment of neuropsychiatric disorders. • Eyes closed resting EEG, 1-2 minutes, 19 sites 10-20 • Treatment response prediction! • Example: • Obsessive compulsive disorder: 2 subtypes • With increased alpha, decreased theta • 80% patients treatment responsive • With increased theta, decreased alpha • 85% patients treatment nonresponsive

  4. Invited lectures: Paolo Maria Rossini(Institute of Neurology, Catholic university, Rome, Italy) • Neurophysiological techniques for cortical connectivity • Network modeling – 3 types of network • Regular • Small-world • Random • 3 levels of cerebral networks • Individual neuron/synaptic connections • Neuronal populations (columns) • Different brain regions

  5. Invited lectures: Giacomo Rizzolatti(University of Parma, Italy) • The mirror mechanism: A mechanism for understanding others • Mirror neurons discharge both when the monkey executes a motor act and when it observes another individual (a human being or another monkey) performing the same or a similar motor act These neurons do not discharge in response to the simple presentation of food. They also do not discharge, when the monkey observes hand actions mimicked without the target object.

  6. Invited lectures: Andrew Papanicolaou(The University of Texas-Houston Health Science Center, USA) Forty years of MEG 44 года назад – первая запись магнитной активности мозга Увеличение количества датчиков Задачи: Определение связей в мозге на различных этапах онтогенеза, поиск специфических для различных заболеваний паттернов Поиск источников эпилептической активности (перед операцией) Локализация речевых, моторных, сенсорных областей

  7. Invited lectures: Lamberto Maffei(University of Pisa, Italy) Environmental enrichment and neural plasticity Environmental enrichment - > visual development massage therapy favours a process of maturation of brain electrical activity Delta, beta ↑

  8. Didactic lectures: Thomas F. Collura(Brainmaster Technologies, Inc., Bedford, USA) Individualized assessment and treatment using advanced EEG and dynamic localization techniques with live sLORETA On-line source analysis Standardized LORETA (low resolution brain electromagnetic tomography ) Pascual-Marqui 19 sites 5mm spatial resolution

  9. Didactic lectures: Risto Näätänen(University of Helsinki , Finland) The mismatch negativity (MMN) - A unique objective index of cognition and cognitive decline in health and disease

  10. Advanced EEG analysis and multi-methodological approaches inpsychophysiological and clinical research Chair: Luis Basile (Brazil) What do the ERP components add to behavioral data? - S. Karakaş, E.D. Dinçer, A.Ö. Ceylan (Turkey) Children 38 normal controls/ 70 ADHD Go/NoGo, Reversal tasks Неправильные ответы -> амплитуда N200 ↑, латентность Р300 ↑ Abnormal brain oscillation as revealed by EEG rhythms in Alzheimer disease: Validation of EEG markers in the European DECIDE project - F. Vecchio, R. Lizio, P.M. Rossini, C. Babiloni (Italy) Болезнь Альцгеймера, ЭЭГ в состоянии покоя. Ранняя диагностика. Lack of systematic topographic difference between attention and reasoning beta correlates - L.F.H. Basile, M.Y. Alvarenga,, N. Henrique Jr., H.A. Pasquini, W. Alfenas (Brazil) Мышление и внимание, бета-волны, метод главных компонент, топография индивидуальна, специализации ассоциативных полей похоже нет.

  11. Symposium B: Oscillatory systems of the brain, their role in the management of mental processes,behavior, and individual differences Chair:Vilfredo De Pascalis, Nina Danilova (Russia) Can training change individual differences in ability? - N. Jaušovec, K. Jaušovec (Slovenia) - > theta desyncronization in frontal areas, theta syncronization in parietal areas, increased intra and interhemispheric coupling. Postest females = males.

  12. The relation of EEG-alpha asymmetry, BIS/BAS, and positive orientation on the trait level - V. De Pascalis, G. Cozzuto, G.V. Caprara (Italy) Behavioral Approach System, Behavioral inhibition System, Positive Orientation (составной индекс), hedonic tone Измерения: Мощность EEG, sLORETA, alpha 8 -13 Hz BIS и hedonic tone не связаны с асимметрией BAS – выше при активации слева в лобных извилинах (BA 10, BA11) Optimism – аналогично (BA10) + BA31 Self-Estimвыше при активации в правом предклинье (precuneus - BA7) Positive Orientation – аналогично

  14. Theoretical aspects and neural correlates of consciousness Symposium Chair: Bruno Rossi Blink-related broad-band EEG oscillations at rest, precuneus and consciousness L. Bonfi glio, M.C. Carboncini, A. Frisoli, A. Piarulli, B. Rossi Blink-related oscillations EEG activity at rest 3s epochcs centered on blink instance sLORETA Normal s – delta, alpha, low-beta -> Precuneus Vegetative state and minimally consicous state -> no delta, no precuneus activity
