The Brain Observatory at UCSD is right now showing the slicing of the brain of an amnesic patient into histological sections on streaming video.
The whole brain of the dead patient (called H.M.) was frozen to -40C and is now being sectioned in a whole-organ microtome during one continuous session that they expect will last about 30 hours. After sectioning the brain they will do ex vivo MRI and so called blockface imaging, and will of course store all the histological sections. The whole sectioning process is streamed on video and will end later today. Watch the live video here.
This is as far as they came at 9.30 am today when I made a screen-dump:
Fascinating histology live!
