I may risk sounding like someone with a chip on his shoulder, but the obsession of the media with brain images is annoying. A recent paper has found that students rate as more credible/scientifically sound the same piece of news if it is accompanied by a brain scan (as opposed to another type of image). The link to a summary is here:
The actual paper in Cognition concludes that it is not so bad because we can use this to attract attention/interest/funding to research in cognition as a whole. Of course the hope is that the interest will not be only on the pretty pictures.
