[Solved] Dr. Franco is using an fMRI to look at brain blood flow while participants are presented with erotic images. After reviewing his results, compared to brain blood flow when no image is presented, he concludes that individuals have a "sex centre" in their brain that is active when erotic stimuli are present. What are at least two flaws in Dr. Franco's design and conclusions? What can be done to improve the experiment?
