A software to measure quantitative electroencephalogram during the performance of a psychological cognitive task using the OpenBCI hardware

Abstract: Quantitative electroencephalogram (qEEG) is used to understand brain functions by processing the activity recorded through the electrodes using different algorithm techniques. The qEEG is commonly known as Brain Mapping. In this paper, we report the development of a software to synchronize the acquisition of EEG signal from the Cyton board with a cognitive task. The digitalized test was done via Psychopy, so the use of LabStreamlayer (LSL) was needed to link with both OpenBCI and LAbRecorder in order to have each stimulus synchronized with the EEG signal. Data was collected from five participants between 20-30 years old while performing the cognitive task. Our results indicate a correct linking of the data recording and the stimuli task, which enables researchers to measure different parameters such as spectral power density, power ban and brain mapping
