Disco Lights?

My surgeon sent me this picture recently. This is the CAT scan of my brain that he took the day before my surgery.

It may look like there's a rave party going on inside my head (and hey, maybe there is), but the top left image is actually a 3D map of the nerves in and around my brain. In fact the coloured lines on all the pictures are critical nerve paths.

Armed with this 'map' and some other very advanced technology, he navigated his way around the inside of my head for 10 hours straight to remove my tumour. This wouldn't have been possible just 10 years ago because the technology just wasn't there. I still find the whole technological part of this whole thing to be simply incredible. The timing of my treatment is fortuitous to say the least.
