Mark Solms and some his theories have come up a few times as topics.
I've written a review of his book so I thought I would pass along a link in case anyone was interested. This is on the scientific side and makes no metaphysical claims. Think of it more in spirit of looking for correlations in the brain image and how the alter works if you need to have that perspective. Since BK and Solms have a shared interest in Friston's free energy theory, it should be relevant.
