Found out about Dr Panksepp through the work of Dr Grandin, discovered the 7 core emotion systems ...system, got excited, bought the book, here we are. I'm very excited about this not only because I'm fascinated by the similarities in cognitive processes and emotions of all mammals, but because it covers in a pretty rigorous way some stuff that gets talked about a lot of polyvagal theory that is often dealt with in a ... perhaps less rigorous way? (Depends on your framework and point of view, I guess.)

In any case, following this rabbit hole to see where it goes.
