There are many techniques that are being used today to examine the functionality of the human brain. Most of the current technologies emerged in early 1990s. Some of the technologies that are used for brain imaging include; computed tomography (CT), positron emission tomography (PET), Magnetic resonance imaging (MRI), event-related potentials (ERPs) and magnetoncephalography (MEG). This paper will look at the history of these techniques used for brain imaging(Katz & Alexander 1994). 1895 – 1900 Early uses of brain imaging The process of imaging human dieses started in 1895 following the discovery of Wilhelm Roentagen.
