Brain Science Podcast #46 is a discussion of brain imaging with Dr. Shella Keilholz and Dr. Jason Schneiderman. The focus of our discussion is functional magnetic resonance imaging (fMRI), which is revolutionizing neuroscience. We talked about both the strengths and weaknesses of this technique. Both of my guests agree that mainstream coverage of this technique tends to exagerate what we can actually tell from this kind of brain scan. An important principle is that the scan of any single individual can vary greatly from day-to-day, which means that valid conclusions require data from a large number of people.
