BoingBoing links to the jaw-dropping Museum of Fabric Brain Art:

This is the world’s largest extant collection of anatomically correct fabric brain art. Inspired by research from neuroscience, dissection and neuroeconomics, our current exhibition features three quilts with functional images from PET and fMRI scanning and a knitted brain. The artists are Marjorie Taylor and Karen Norberg. Techniques used include quilting, applique, embroidery, beadwork, knitting, and crocheting. Materials include fabric, yarn, metallic threads, electronic components such as magnetic core memory, and wire, zippers, and beads.

It’s seriously beautiful stuff. And I have to admit, the disclaimer on their site really cracks me up:

While our artists make every effort to insure accuracy, we cannot accept responsibility for the consequences of using fabric brain art as a guide for functional magnetic resonance imaging, trans-cranial magnetic stimulation, neurosurgery, or single-neuron recording.
