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


Invited lectures leslie prichep brain research laboratories ny university school of medicine
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


Invited lectures paolo maria rossini institute of neurology catholic university rome italy
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


Invited lectures giacomo rizzolatti university of parma italy
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.

The mismatch negativity (MMN) - A unique objective index of cognition and cognitive decline in health and disease


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.


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.


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
