Robin, I don't want to jump the gun on the longer piece I will (probably co-)write, but how well do you understand the plastic embedding process? You say "
But for brains filled with plastic within a few minutes of live blood flow, I just cant see the problem." Within a few minutes? How are you going to perfuse with aldehydes, then osmium tetroxide, then ethanol in a few minutes. It's going to take hours. Then more days -- not hours -- to perfuse with resin.http://www.overcomingbias.com/2012/07/brain-prize-fund-near-enough.html#disqus_thread
