fMRI Claustrophobia

The fourth hack explains what fMRI is and what it's used for. fMRI stands for functional magnetic resonance imaging and is a technique to map brain activity. It gives a very clear 3-D image of brain activity by 'push[ing] the hydrogen atoms in your brain into a state in which they all "line up" and spin and the same frequency.' That just doesn't sound good for your brain, even tho' this technology has been around for a couple decades. Basically, anything that greatly changes the way your body function at the elemental level makes me very wary.

On the flip-side, it seems that the technology is progressing even further and being integrated with other technologies to make of for some of its failings. The Wikipedia article has a good overview.
