"My Brain Is a Walnut" - Inside a functional MRI machine

When I was a resident, I also participated in a study in a functional MRI. I still have the images. Via Slate:

"If we find any gross abnormalities in your brain, would you like a radiologist to tell you about it?" Tobias Egner asks me. He is about to wheel me into the dark gullet of an fMRI machine at the Functional MRI Research Center at Columbia University, a leading neuroscience lab where he is a research fellow. I say yes to his question and ask if anyone ever says no. "If you answer no, we cannot do the test," Egner says. He speaks with a soft certainty and a German accent; if this were a movie, he'd be played by Willem Dafoe, a la The Life Aquatic With Steve Zissou. "Ready to roll?"
