Neuroimaging

Neuroimaging consists of a specific group of biological living tissue imaging methods aimed at imaging the living brain. These are used to determine the structure of the brain, or more frequntly, to determine how information is processed by the brain, by following the activiy patterns and oxygen supply patterns of thoughts in real-time.

Neuroimaging is also essential for the placement of all neuroprosthetics. The specifics of an individual brain must be clarified so that an exact siting for the electrodes of any neuroprosthetic can be carried out with pinpoint accuracy.

Should an individual with an active neuroprosthetic implanted in their head begin showing strange behaviour patterns, neuroimaging techniques are the first point of call in any investigation, as such behaviour modification is often the result of an electrode of the neuroprosthetic which has shifted position in the brain, and is now interfacing with the wrong group of neurons.

Neuroimaging techniques are an area which is continually under a high degree of refinement, with a wide variety of techniques avalable and a great deal of research investment. Much of this is so that the neuroimaging capabilities available to us can keep pace with general brain research and the increasing precision of placement needs of the various neuroprosthetics.

Due to the extreme complexity of the brain and the need for such pinpoint placement of neuroprosthetics, the data produced by neuroimaging methods is increasingly then imported into a three-dimensional medical virtual environment, where the data may be dissected in any way, often beyond the capabilities of the original imaging method used to gather the data.

In this way, the line between virtual reality itself, and the imaging systems used to create the implants for direct interfacing with computer systems (including virtual reality systems) is effectively becoming increasingly difficult to discern.
