Female sexual arousal disorder presented research findings based on neuro-imaging of women's sexual function. In a small pilot study of four women with female sexual arousal disorder, Maravilla reported there was less brain activation seen in this group, including very little activation in the amygdala. These women also showed increased activation in the temporal areas, in contrast to women without sexual difficulties, who showed deactivation in similar areas. This may suggest an increased level of inhibition with an arousal stimulus in this small group of women with FSAD. Several types of medications, including selective serotonin reuptake inhibitors (SSRIs), can cause sexual dysfunction and in
