With magnetic resonance imaging (MRI) brain scans becoming as common as family photos at Sears (maybe even more common), it's no surprise that Flickr is packed with people eager to share pictures of their comely cortical wrinkles. Sometimes these images are goofy ("check out my eyeballs, dude!"), and sometimes quite poignant ("this is my brain after they removed a deadly tumor"). See more publicly-shared medical images after the jump.

No matter what, I like any trend that leads us closer to a day when people flirt online by exchanging MRIs of their brains.
