Abstract
This work has been carried out to support the investigation of the electroencephalogram (EEG) Fourier power spectral, coherence, and detrended fluctuation characteristics during performance of mental tasks. To this aim, the presented dataset contains International 10/20 system EEG recordings from subjects under mental cognitive workload (performing mental serial subtraction) and the corresponding reference background EEGs. Based on the subtraction task performance (number of subtractions and accuracy of the result), the subjects were divided into good counters and bad counters (for whom the mental task required excessive efforts). The data was recorded from 36 healthy volunteers of matched age, all of whom are students of Educational and Scientific Centre “Institute of Biology and Medicine”, National Taras Shevchenko University of Kyiv (Ukraine); the recordings are available through Physiobank platform. The dataset can be used by the neuroscience research community studying brain dynamics during cognitive workload.
Highlights
This work has been carried out to support the investigation of the electroencephalogram (EEG) Fourier power spectral, coherence, and detrended fluctuation characteristics during performance of mental tasks
Many theoretical and practical works have been published over the last decades about the relationships between cognitive phenomena and activity of brain structures [1], the “global workspace” theory of brain functioning during emotions and mental activity [2], dynamical properties of cortical areas and their coordination [3], and brain networks interaction during creative cognition and artistic performance [4]
The activation of functional and anatomical brain areas during cognitive activity has mainly been studied by the standard techniques of spectral [9,10] and coherence [11,12] analysis, which are well-established and powerful tools used to reveal the important characteristics of brain functioning
