Clinical psychologists and neuroscientific researchers have always sought to understand what is going on in the brain and what is on the mind of their clients. For centuries, direct examination of the brain was elusive and almost nearly impossible due to the inadequacy of technology. However, noninvasive advances in brain examination have alleviated those challenges, making it possible to explore and investigate the brain in depth.

The first EEG was developed in the 1920s by Hans Berger, which was first used in 1924 to assess electrical current in the brain. Electroencephalography is conducted when electrodes are placed and attached to the scalp;
