Ciklum’s AI Experts Release A Scientific Study On Brain Activity

Ciklum’s AI technical lead, Anton Popov, and IoT research engineer, Ivan Seleznov, along with five other researchers published a scientific study “Electroencephalograms during Mental Arithmetic Task Performance” in a special issue of Big Data and Digital Health on January 18th, 2019.

The seven researchers from Kyiv, Ukraine and Osaka, Japan conducted an investigation into electroencephalogram (EEG) Fourier power spectral, coherence and detrended fluctuation characteristics during performance of mental tasks. In neuroscience the activation of cognitive function is studied by spectral and coherence analysis. Anton with the group of researchers decided to go further and explore the new possibilities of nonlinear digital signal processing techniques such as detrended fluctuations and entropy by collecting electroencephalogram data from subjects performing cognitive tasks.

The researchers recruited 36 student volunteers and took the participants through a series of arithmetic tasks. This was accompanied by inducing changes in their emotional states, so this study also addresses brain activity dynamics during evoked emotions. Based on the accuracy of the computations the recordings were divided into optimal and sub-optimal (when mental tasks required additional efforts).

Understanding a brain’s computational activity while it performs various mental tasks enables us to get a closer look at the brain’s architecture. The recordings we made can be used for studying the involvement of different brain areas in cognition processes and nonlinear characteristics of brain dynamics.

All the recordings are available through the Physiobank platform and can be used by the neuroscience research community to study brain dynamics during cognitive workloads and emotional experiences.
