Study of tissue is typically not just a study of morphology. (02)
yes, but a biopsy can be done with just a few cells - right? (03)

I have looked it up, its a very simple creature :-)
I am not sure it has got a 'mind', what do you think? (05)

I think so too, but, why? what makes the human more interesting than a nanopode
Or is it consciousness that we are looking for? and where would that stored?
any results yet? (07)

yes, thats what I mean (09)

should be able to work on that (011)

I'd love to look inside my brain while I am still alive
Where can I buy the electrodes? and download the analyzer software so
that we can monitor it while I am online going through my normal
processes? (013)
and oh, dont forget to tell me where to ship my brain when it becomes available
provided its treated nicely and preserved appropriately and studied as a whole
maybe thats one way to serve science after we are gone (014)
