The aim of the present work was to study the characteristics of cortical interactions during performance of an image-based creative task in men and women with high and low levels of creativity. Subjects were divided into groups on the basis of the median originality score. EEG recordings were made in baseline conditions and during performance of the task(More)
BACKGROUND Significant (>70%) extracranial stenosis of the internal carotid artery (ICA) is a known risk factor for brain damage in patients with coronary heart disease (CHD) undergoing coronary artery bypass grafting (CABG). There is no clear evidence of the low and moderate ICA stenoses influence on the neurophysiologic status of patients after CABG. This(More)
EEG correlates of imaginal creative activity and its effectiveness after the instruction “create an original solution” (INS1) alone and with the promise of monetary reward for good results (INS2) were studied. Right-handed subjects (15 men, 16 women) took part in the study. The task was the Torrance “unfinished figure” subtest. As compared with INS1,(More)
Creativity-related changes in alpha power in low-frequency (8-10 Hz) and high-frequency (10-13 Hz) bands were studied in university students having regard to generation of original ideas during performance of two verbal tasks. A high-creative group enrolled 16 subjects asked to generate original words--associates to the triads of verbal stimuli and 14(More)
The aim of the present work was to undertake a comparative evaluation of changes in the neurological and neuropsychological status of patients with and without carotid artery stenoses of less than 50% after coronary bypass. A total of 65 patients were assessed, in two groups: group 1 did not have carotid artery stenosis and included 35 patients (mean age(More)
Electroencephalogram (EEG) changes associated with on-pump coronary bypass artery grafting (CABG) for ischemic heart disease (IHD) were studied in 28 right-handed men, 10 of whom had concomitant moderate (30–50%) carotid artery stenosis. EEG studies were performed 3–5 days before and 7–11 days after surgery. The control group consisted of 14 healthy men of(More)
The aim of this study was to compare the effects of stimulating originality verbal instruction (IN1) and monetary reward (IN2) on originality of solutions of a verbal creative task and EEG-correlates of activity, determined on the basis of biopotentials power mapping in the frequency range 4-30 Hz. Right-handed students (10 men and 10 women) took part in(More)
The severity of angiographically assessed coronary artery disease may be the factor that influences the degree of brain damage during on-pump surgery. Modern technology such as computed electroencephalography (EEG) that is used to detect signs of brain damage could also be used to determine the advantages and disadvantages of various surgical myocardial(More)
Analysis of EEG correlates of figural creativity (Torrens "Incomplete figures" subtest) and its efficacy after the instruction "to create an original solution" (condition I) and after the same instruction with the promise of a monetary reward for high performance (condition II) was carried out. Fifteen right-handed men and 16 women were examined. In(More)
