Abstract
Abstract: The aim of the present study is to collect the electrical activity of the brain using electroencephalogram (EEG) data from subjects performing a cognitive workload task. During the study, the subjects were involved in intensecognitive activity while performing mental calculations (serial subtractions). The background EEG was recorded from each subject. The primary aim for collecting this dataset is to conduct fluctuation analysis of the EEG duringcognitive activity and to compare the result to the data provided by conventional methods, such as Fourier power spectral density mapping and coherence. It can also beutilized for studying the time-scale characteristics of the involvement of different brain areas in cognition processes and nonlinear characteristics of brain dynamics.
