Well, I know precious little about neuroscience, but from my EE background I can certainly agree that it's the connections between gates that make a circuit do what it does. Only it's called by a less fancy term, schematics. Maybe I should start calling it "connectome".
Sebastian Seung's new book Connectome: How the Brain's Wiring Makes Us Who We Are is very well-written, and aimed at a broad audience.
The penultimate chapter explains why cryonics might make sense given our current understanding of the brain.
The final chapter does the same for mind uploading.
Transhumanism continues its march into the mainstream.
Despite its flaws, I recommend the book.
