Are they saving the slices or just photographing each layer as it's cut down?

Are they saving the slices or just photographing each layer as it's cut down?
- Devilboy 17y agoI'm pretty sure they just care about the photographs at this stage.
- aarongough 17y agoThat's what I thought as well... I don't think the slices themselves would be much (if any) more useful than just dissecting the brain normally...
- ars 17y agoWatch the video link posted by Ezra http://news.ycombinator.com/item?id=973677 http://news.ycombinator.com/item?id=973677 and you can see what they do with each slice. They store it in a tray with square holes (all bunched up). Later they remove it, wash it, mount it on glass, and stain it. Then it goes under an automatic microscope that scans it.
- aarongough 17y agoWow, thanks! From the way the slices were bunched up I (wrongly) assumed they were basically getting thrown away. But I guess not!
- trobertson 17y agoI believe they will preserve the slices cryogenically. http://thebrainobservatory.ucsd.edu/hmblog/?p=66 http://thebrainobservatory.ucsd.edu/hmblog/?p=66
