In this episode of PNM, reporter Matthew Zmudka is “thinking about thinking” with two stories on brain imaging. In the first, he talks to Andrew Nencka, assistant professor at the Medical College of Wisconsin, on a technique called fMRI that, without dyes or radioactivity, can track areas of brain activity. Then, he visits with Angela Richardson, Artist-in-Residence at the Wisconsin Institutes for Discovery’s Image Lab, about her new exhibit looking at the history of images of the brain.

Angela is chronicling her exhibit on a Tumblr blog, The Great Ravelled Knot, and was kind enough to mention this show there. Check it out for many of the pictures mentioned in the broadcast, as well as for a questionable picture of the reporter.
