Abstract

Purpose

The purpose of this paper is to analyze the results of recording electrophysiological signals by nanosensors during tests on volunteers using neutral questions and questions that cause excitement.

Design/methodology/approach

The nanosensor-based hardware and software complex (HSC) was used for simultaneous recording of electrocardiogram, electroencephalogram and galvanic skin response during tests on volunteers using neutral questions and questions that cause excitement. The recording was carried out in real time without averaging and filtering in the extended frequency range from 0 to 10,000 Hz, level of more than 1 µV and sampling frequency equal to 64 kHz.

Findings

For the first time, the following signals were recorded by nanosensors without filtering and averaging in the measuring channels: real-time micropotentials on an electrocardiogram with a duration of 0.2 ms and a level of 1 µV or more. Also, for the first time, changes in the shape and amplitude of the P wave, slow waves on the electroencephalography (EEG), high impulse activity of the EEG and impulse activity of short duration on the GSR were recorded in response to questions that cause excitement.

Practical implications

The obtained results will be used for high-resolution equipment to develop additional measuring channels in existing types of equipment for psychophysiological studies.

Originality/value

For the first time, new data undistorted by filters was obtained on the amplitude and time parameters of electrophysiological signals in the frequency range from 0 to 10,000 Hz in response to questions that cause excitement, which was due to high sensitivity and noise immunity of nanosensors in comparison with existing electrodes for biopotential recording.

Abstract

Purpose

This study aims to explain and illustrate the character of Russian systems thinking and to show how it is different and similar to traditions in the West. This study’s second aim is to describe the contributions of some Russian scientists to developing systems thinking and the theory of evolution. This study introduces the predecessors of Charles Darwin in Russia, both supporters and critics of his ideas, as well as scientists who have made similar contributions to the development of systems thinking, particularly Vladimir Vernadsky and Alexander Bogdanov.

Design/methodology/approach

Philosophical and theoretical comparisons. In the Russian intellectual tradition, the terms “Russia” and the “West” are likely codes for signifying fundamental philosophical questions about the universality of thinking and culture. The term “West” means universal, rational truth without taking into consideration any differences in life and cultural practice. The term “Russia” means impossibility of such a universal truth and a necessity to look for solutions on the level of life, not only on the level of rational thinking.

Findings

Paying attention to differences in approaches to systems and cybernetics and the theory of evolution will enrich the further development of systems sciences in Russia and the West. The paper examines the philosophical underpinnings of science rather than just testing or extending an existing theory. The result is better mutual understanding among scientists with different backgrounds.

Originality/value

This study suggests new avenues for research and expands the range of conceptual possibilities. It improves mutual understanding among scholars and countries. Also, it adds to the topics discussed within the field of systems and cybernetics and the theory of evolution.
