![]() In the second part of this chapter we will survey examples of the application of virtual reality and brain imaging methods to clinical populations. These tasks are spatial navigation, car driving, and social interactions. ![]() In the first part of the chapter we will describe brain correlates of a few examples of tasks that are very difficult, if not impossible, to employ inside a brain imaging scanner without virtual reality technology. This chapter provides an overview of these kinds of studies that employ both virtual reality and brain imaging technologies. In a very different type of therapeutic application, virtual reality is also being developed to augment clinical use of brain imaging results for presurgical planning. Virtual reality is also being developed as a therapeutic tool for a wide range of clinical populations, and because the brain is a primary mediator of effects of virtual reality treatments brain imaging is an important method for assessing some types of treatment effects. Virtual reality is compatible with many brain imaging methods and this has allowed researchers to evaluate typical and atypical brain function when users are immersed in a virtual reality environment. Thus virtual reality technology makes it possible to simulate an environment with better ecological validity and control than previously possible for brain research and clinical applications. Virtual reality is an evolving technology that allows for the possibility of interactive environments with stereoscopic, three-dimensional (3D) visual displays, auditory input, haptic feedback, and immersive interaction from a first person perspective.
