EFFECTS OF REAL AND IMAGINARY HAND MOVEMENTS ON EEG

Abstract

Our brain is one of the most complex structures in the known universe, and no matter how we want to make it simple, the way of work of it is quite complicated. In this study, the brain's structure and function that enable our movements were briefly discussed. Electroencephalography (EEG) is a non-invasive method of examination in which spontaneous electrical activity of the brain is recorded through electrodes. This examination reflects the current functional state of the brain rather than its structural properties.This study is based on an analysis of EEG signals obtained through a subject raising his left and right arm forward and then imagining him raising his left and right arm forward. First, the change of signals by the time was obtained, then the amplitude spectra of EEG signals were reached by applying the Fast Fourier Transform. Finally, the power spectrum analysis of signals was performed using the Welch method.
