Virtual reality (VR) is a concept that uses multiple novel approaches to allow interaction with human sensorimotor and cognitive systems. It is a global approach toward the temporary fusion of experience and function with an artificial environment in which the links to reality fall to a large extent under the control of the VR designer. To achieve these ends, VR systems produce high levels of immersion, or the perception that the subject has entered into the "world" constructed by a set of computer-generated stimuli. Moreover, the computer (which in the strict etymologic sense refers to a thinking aid) takes on the additional role of an experience enhancer.

The interactions of the VR milieu now are emerging in attempts to understand and intervene in a variety of neurologic disorders.
