Methods of Acquisition, Archiving and Biomedical Data Analysis of Brain Functioning

Abstract

The following article sets out four acquisition methods of data obtained on the basis of brain signals: EEG, NIRS, fMRI as well as PET. Moreover, it provides the readout analysis of the signals occurring within the human brain and a possible manner of archiving and processing them. For an illustrative readout of the signals, a multi-channel encephalograph was applied. With the use of Emotiv Xavier TestBench application, time-varying EEG signals from individual electrodes were recorded in the.edf format which were subsequently subjected to Toolbox EEGLab for Matlab.
