The individual differences in the autonomic support of intellectual activity, including simple and complex sensorimotor reactions, memorization and reproduction (on the screen of the monitor) of visual information, were studied. The rate of performing intellectual computer-aided tests is a relatively steady individual characteristic revealed in different(More)
The basic somnological methodology, which is extensively used in the present time, focuses only on clinical practice. However, this approach is not appropriate for monitoring of physiological functions during natural sleep under home conditions. Our work was designed to develop a new information-and-equipment device for the reliable study of human(More)
RATIONALE Pseudoprogression, that is, initial tumor growth followed by subsequent tumor regression, has been well described for immunomodulation therapy in melanoma patients. This phenomenon is not well defined in lung cancer. Nivolumab, an anti-PD-1 monoclonal antibody, was recently approved for nonsmall cell lung cancer (NSCLC) as a second-line therapy.(More)
Crizotinib achieves excellent systemic control in anaplastic lymphoma kinase-rearranged (ALK+) non-small cell lung cancer (NSCLC); however, central nervous system (CNS) metastases frequently occur as an early event. Whole brain irradiation, the standard treatment, results in neurocognitive impairment. We present a case series of three ALK+ NSCLC patients(More)
We studied spatial organization of EEG alpha range potentials in volunteers with different results of tasks requiring logical thinking. The examinees with higher cognitive test performance have more labile coherent associations of EEG alpha range potentials, which manifested in changes in the level and structure of these associations at different stages of(More)
Changes in the power and coherence of α-activity and heart rate variability (HRV) were studied in students with different performance levels in logical tasks. In those students who reached high scores in the cognitive tests, we observed higher lability of α-activity and HRV; the values and their ratios varied among the stages of intellectual activity. In(More)
Changes in the power and coherence of α activity and heart rate variability (HRV) were studied in students with different performance levels in logical tasks. The students achieving high results in cognitive tests exhibited higher liability of α activity and HRV; the values and their ratios varied among the stages of intellectual activity. In these(More)
Heart rhythm variability characteristics were studied in volunteers with different stability of the results upon switching from one type of intellectual activity to another. Individuals with stable results differed from those with worse accuracy of information reproduction by high initial CV, total power of heart rhythm variability and power of VLF, LF, and(More)
