This article presents the recording and analysis of the electrical activity of EEG signals in situations of cognitive load, stress and emotion recognition as part of a doctoral research that was carried out with a focus group of Colombian university professors of experimental sciences. One of the purposes of the study was to analyze the physiological changes in the electrical activity of the brain due to teaching activities that involve cognitive load, stress and the recognition of emotions that triggers this process for the group of teachers. To acquire the rhythms of the EEG signals, a device called Emotiv EPOC+ was used and a group of psychometric tests adapted to induce electrical signals that helped us relate them to the teachers' tasks. We use various mathematical functions to analyze and classify the obtained signals.
