That is the thread of this that I would pull if I had a spare platoon of researchers to send into this territory. How distinctive a memory is "implantable"? As it is, I guess we will just have to wait until someone else does that work.

Speaking of... is there some good way to get notified when a paper is published which builds on some known body of work? Like can I get an email digest updating me if any of a set of papers are referenced in new papers?

Addendum: Yes... "Track Citation" on JSTOR does this (if one makes an account)... I doubt it does a pretty digest that helps me remember why I wanted to know about the new papers (what question about the original paper I was interested in having future research nail down), but it will have to do for now.
