Right Inferior Frontal Gyrus is Involved in the Processing of Visual Sezual Stimuli: an fMRI Study
Visually-induced sexual arousal evoked by erotic film or picture is a common occurrence in human behavior; nevertheless the cerebral underpinnings are not clear yet. In the present study we intend to investigate the brain activation pattern associated with visual sexual stimuli. Functional magnetic resonance imaging is used to investigate 15 female participants’ sexual arousal induced by visual stimuli in film and picture forms, performing three or more times in their one menstrual cycle on a 3.0T magnetic resonance imaging scanner. From the brain activation we got, the inferior frontal cortex or inferior frontal gyrus is found to be hemisphere-specific and task independent. We hypothesize that this cerebral cortex may play an important role in sexual information processing and suggest, for the first time, that the functional lateralization of the inferior frontal gyrus might be bi-direction rather than single (left) direction.
