Re: Emulating a recursive torus frog brain to eat drosophila simulations in 70 milliseconds

Thanks for posting about your progress here. Some people believe that neuromorphic computing may be very important in the future. Myself, I don't have any expertise to say either way. It is very interesting! Best of luck with your endeavors.

What would be the hardest aspect of repair for potential biological revival?

I have been having a lot of discussions with people about the potential for biological revival via molecular nanotechnology in recent weeks. One topic that has come up over and over again is that some people expect that specimens preserved with fixatives will be much more difficult to "repair&q...

Re: ASC vs. O.C. $1K aldehyde bath + molecular brain scan

My current view is that storage via chemical fixation alone is likely to be adequate if it is either formaldehyde or glutaraldehyde, but the addition of glutaraldehyde will likely be helpful because it is an even stronger covalent crosslinker, to help stabilize the tissue.

Re: Dendritic Spine Retraction

The information is definitely not encoded in the nucleus, that's true. So your claim is that all dendritic spines retract and synapses are lost within 5 minutes of complete global cerebral ischemia? This seems pretty inconsistent with the available evidence. See, for example, the section of our revi...

Re: Sunsetting the research program for new sign ups

I don't think it's a significant loss from a research perspective. We already have a lot of brain tissue available to us. Our bottleneck is our ability to characterize it.

Also, I think most people don't want biopsy samples of their brains taken.
