Stephan Hamann and Kim Wallen, along with psychology graduate student Rebecca Herman, are collaborating on a project to study neural responses to visual sexual stimuli. In order to do this, they use Functional Magnetic Resonance Imaging (FMRI), a technique for measuring brain activation using an MRI scanner. This technique capitalizes on the fact that increased neural activity requires increased blood flow; changes in blood flow show up on the FMRI scans.
Fourteen males have participated in this project by viewing pictures while having their brains scanned. Subjects viewed arousing images and non-arousing images blocked in 20-second intervals; in other words, for 20 seconds they viewed arousing pictures, and then in the next 20 seconds they viewed non-arousing pictures, alternating for several trials. There were also trials that alternated every four seconds.
There wasn't no data I saw on the website about the results. Will have search the topic futher.
