Electroencephalography y or otherwise known as EEG is what is used to record electrical recording of the brains spontaneous electrical activity either for diagnostic application or for research and this is one of the test that is used to measure extra-sensory perception or to clairvoyant readers.

In the modern times encephalography is used to test epilepsy, comatose, stroke, tumors, and focal brain disorders and the course of the mentioned diseases. It can also be used to measure and test visual, auditory and somatosensory activities which are the basis for the studies of clairvoyant readers and extra-sensory perception in psychological studies, and cognitive studies especially scalp electroencephalography activity.

In an effort to establish a clear connection between reality and supernatural world scientist often uses machines that can help them in their study with clairvoyants and how clairvoyant readers are able to view the things that were considered not normal or at least hear things that were inaudible to ordinary human ears.

There are many advantages tests or research studies over clairvoyant readers using electroencephalography and they include ease and convenience especially since electroencephalography is relatively silent allowing better study and concentration and better yet you dont have to put the patient or the subject in a close area causing claustrophobia and because patient or the subject is allowed to do some slight movement and it gives higher resolution of milliseconds and the machine can be transferred from one place to another and can detect even covert processing.

Electroencephalography started out to read wavelengths by amplifying frequencies which will show a typical peak when the subject looses consciousness. Electroencephalography is not only used to study supernatural events and use to test whether they real or not or what is really going on inside the clairvoyants body and the reaction the body is undergoing and the response it is giving to stimulus.

It was once believed that a person goes into trance and into the state of being a clairvoyant when that person enters the highest spiritual learning as a result that person acquires psychic abilities and extra-sensory perception. Electroencephalography or otherwise known as EEG is not only used in the study of clairvoyants and clairvoyant readers but also is used in many fields of medicine but this is the preferred machine that scientist who are studying paranormal phenomenon use more often compared to other sophisticated machines.
