The Effects of in Vivo Exposure Therapy on the Neural Correlates of Height Phobia: a Functional Magnetic Resonance Imaging Study Using a Fear Provocation Paradigm.

The purpose of this study is to investigate the effects of in vivo exposure therapy on the functional brain activity of subjects with height phobia using a fear provocation paradigm. We expect differential activation of the fear circuitry in height phobics compared to non-phobic controls, and that successful behavioral therapy will normalize the heightened fear response in height phobia.
