ORIGINAL RESEARCH-ANATOMY/PHYSIOLOGY: Assessment of Sexual Orientation Using the Hemodynamic Brain Response to Visual Sexual Stimuli

Despite the small sample size, the functional response patterns of the brain to sexual stimuli contained sufficient information to predict individual sexual orientation with high accuracy. These results suggest that fMRI-based classification methods hold promise for the diagnosis of paraphilic disorders (e.g., pedophilia).
