    Renowned scientist and philosopher Galvani was the first person to discover electrical activity in living organism in the 18th century [1]. And later the celebrated electro physiologist Hans Berger successfully recorded electrical activity from the human brain using electroencephalography (EEG), which measures voltage oscillations due to ions flow in the neurons of the brain [1]. Today, EEG is one of the popular non-invasive techniques to record brain activity in clinical and research settings, and there is a wide range of cheaply accessible applications for the analysis and interpretation of these measurements. EEG data carries an immense potential in its usability in various areas including human computer interaction, psychology, and neurological…
