Somewhere, over the brainbow... November 1, 2007 3:09 AM Subscribe
Brainbow.Using some very cool genetic tricks, Harvard scientists have found a way to make transgenic mice that express various mixtures of different coloured fluorescent proteins in their neurons. The result, individual brain cells with up to 90 distinct colours. Not surprisingly, this visually impressive work is in this month's issue of Nature.

I work for a company that produces stereology and neuroscience software. I knew about fluorescent stains, but this is just fascinating to me! Thank for the link! posted by paddbear at 3:14 AM on November 1, 2007
i wish they had whole-brain cross-sections/ 3-d views...it would be interesting to see if the large scale patterns look anything like some of these posted by sexyrobot at 3:37 AM on November 1, 2007

You wish. Leave the poor mice alone and drop some acid instead. posted by three blind mice at 4:45 AM on November 1, 2007
Eminently useful. posted by DU at 4:53 AM on November 1, 2007
That is really cool! Thanks for providing the full-text links; I will have to find out if the neurosurgeon I am working with today has seen them. posted by TedW at 5:08 AM on November 1, 2007
Whatever the utility, that is some of this most beautiful art I've seen. It is a real reflection of the brain, just as art is a reflection of the mind of the creator. posted by stbalbach at 7:36 AM on November 1, 2007
This is just awesome. I think I'll present it to my lab on Monday. posted by gaspode at 7:39 AM on November 1, 2007
Sexyrobot: The way this works is that each cell has a random color, so whilst this is an exciting technique for following the paths of individual neurons and whatnot, you'd not expect there to be a higher order pattern. A whole-brain image would just look like the average of all the available colors - presumably white. But what incredibly beautiful pictures. I'm trying to imagine a useful way to incorporate this technique into my own work. posted by nowonmai at 8:04 AM on November 1, 2007
Those are some mighty tasty looking photos. Thanks much. What's for desert?
The beauty aside, I confess I am not entirely comfortable with advances in this science. My brain/mind/thoughts are my final fortress. Any notion of it's potential breach is disturbing. I hate being any kind of ludite. I respect science, deeply. But if we get to the point we can no longer be secure in our minds, humanity itself is lost.
But such fascinating science, none the less. posted by Goofyy at 9:39 AM on November 1, 2007
This is awesome. Lichtman and Sanes are really good at what they do and this paper just takes it to the next level. The images are beautiful, the technique is elegant, and it's a very powerful tool. posted by pombe at 9:48 AM on November 1, 2007
