Studies in 20 healthy right-handed subjects analyzed evoked EEG synchronization and desynchronization in the delta, theta1, theta2, alpha1, alpha2, beta1, beta2, beta3, and gamma ranges in response to sequential presentation of stimuli from the International Affective Picture System (IAPS) with low, medium, and high emotional activation impact. Each signal(More)
Event-related desynchronization (ERD) and synchronization (ERS) in the theta frequency band was measured while subjects viewed stimuli with differing emotional content (from the International Affective Picture System). A significant valence by hemisphere interaction emerged only in the anterior temporal regions, showing relatively greater right hemisphere(More)
Event-related desynchronization (ERD) and synchronization (ERS) in the individually defined theta, alpha-1, alpha-2 and alpha-3 frequency bands were measured in 20 healthy subjects in response to International Affective Picture System (IAPS) stimuli with low, moderate and high arousal (LA, MA and HA) content. The 62-channel EEG, skin conductance response(More)
Event-related desynchronization (ERD) and synchronization (ERS) in the individually defined theta, alpha-1, alpha-2, and alpha-3 frequency bands were measured in 22 healthy subjects (Ss) in response to neutral (Neut), emotionally positive (Pos), and negative (Neg) IAPS stimuli. The 62-channel EEG, facial EMG and ECG were simultaneously recorded while(More)
The 62-channel EEG was recorded while control non-alexithymic (n=21) and alexithymic (n=20) participants viewed sequentially presented neutral, pleasant and unpleasant pictures and subjectively rated them after each presentation. The event-related synchronization (ERS) to these stimuli was assessed in the theta-1 (4-6 Hz) and theta-2 (6-8 Hz) frequency(More)
The main objective of the present investigation was to examine whether trait anxiety construct would influence EEG event-related synchronization (ERS) of the theta power during viewing of visual threatening stimuli. The 62-channel EEG was recorded while low (LA, n= 18) and high (HA, n= 18) trait-anxious subjects viewed sequentially presented neutral,(More)
The main objective of the present investigation was to examine how high trait anxiety would influence cortical EEG asymmetries under non-emotional conditions and while experiencing negative emotions. The 62-channel EEG was recorded in control (n=21) and high anxiety (HA, n=18) non-patient individuals. Results showed that in HA subjects, the lowest level of(More)
The defensive cardiac reflex (DCR) is a reaction of the cardiovascular system with a specific profile of short- and long-latency reactivities (mainly of arterial blood pressure (BP) and heart rate (HR)). The DCR reflects activation of the defensive motivational system and defensive coping programs in humans. The aim of the present work was to evaluate the(More)
The influence of citicoline, phenylpiracetam, pentoxifylline and N-phenylacetyl-L-prolylglycine on cognitive processes and functional state of mitochondria in the neocortex of alloxan-diabetic rats has been studied. The drug effects on cognitive processes were assessed using passive avoidance tests in the dark-light camera. Latent period and the number of(More)
The 62-channel EEG was recorded while low (LA, n = 18) and high (HA, n = 18) trait-anxious subjects viewed sequentially presented neutral, threatening and pleasant IAPS stimuli. Event-related desynchronization (ERD) and synchronization (ERS) were studied in the delta, theta1, theta2, alpha1, alpha2, beta1, beta2, beta3, and gamma frequency bands.(More)
