Electroencephalography is an imaging technique that records the electrical activity of the human brain generated by the physiological structures of the human brain (Niedermeyer and Silva 2004). In other words, an Electroencephalogram (EEG) can be defined as the electrical activity of the human brain recorded from the scalp or surface of the human brain using conductive electrodes and conductive media (Atwood and MacKay 1989). All direct and indirect techniques that are used to produce an image of the physiological structure, functions and pharmacology of the human brain are cumulatively known as Neuroimaging (Smith and Kerri 2008). It can be broadly classified into two categories: •Structural imaging Covers the analysis of the physiological and anatomical structure of the human brain (Smith and Kerri 2008). •Functional imaging It is used to evaluate brain functions, often aiming to understand the relationships between specific functions mental states and activities due to these mental conditions technically known as cognitive state of mind within specific brain areas. It implies a...
