This one's for the neuro-geeks:
I've just come across some very cool neurological research that has quite a bit to do with Salvia and after searches for "claustrum" turned up zero results here I wanted to share what I've discovered.
In 2005 Francis Crick, who famously with Watson discovered (with the aid of LSD) the functional structure of DNA, worked on a manuscript with Christof Koch studying a small piece of the brain called the Claustrum. It's a thin sheet of grey matter that spans the majority of the length of the neocortex and sits beneath it. It's unique in the brain. It seemingly takes inputs and outputs from all over the neocortex. Crick suggested that here was possibly the seat of consciousness - the "conductor" of the orchestra of information running through the brain, resulting potentially in "waves" of data through the claustrum which end up resulting in what we experience as SINGLE perception, SINGLE consciousness, compiled from the myriad inputs of the brain network. His manuscript ends with "The neuroanatomy of the claustrum is compatible with a global role in integrating information at the fast time-scale. This should be further experimentally investigated, in particular if this structure plays a key role in consciousness. What could be more important? So why wait?"
He was in fact working on this manuscript in the hospital the day he died.
An interesting aspect of the Claustrum is the unusual density of mRNA for the kappa-opioid receptors in its neurons. Which brings us into Salvia country. Salvinorin A is a very "clean" drug, in that it specifically is a kappa agonist, separating it from the alkaloid psychedelics. The K-receptors are the locks and Salvia is the key, and I think the experience of a high dose of Salvinorin A can be traced to what's happening in the Claustrum.
Picture it, if Crick is right - What you see, hear, and feel is coming into your brain as disparate moving data. The claustrum takes all of this disparate input and allows it to flow in waves - these waves, moment by moment, define your single experience in time.
Anyone who's done a high dose of Salvia knows what happens - That familiar, comfortable "single consciousness" gives way to multiple-consciousness, a feeling of being a multitude of separate selves, able to hive and split into a countless mass of millions or billions or trillions, until... until ???????
It could be that Salvia is disrupting the regular action of the Claustrum, and it's this action that provides much of the strange experience, including the confusion of wildest synesthesia. But the action of breakthrough is of particular curiosity. I recall returning from breakthrough, arriving suddenly into a sudden raging storm of multiple consciousness which is beyond my control until it is synchronized into a single perception that is appropriately taking input from good-old-fashioned-human-consensus reality. The Salvinorin has metabolized and we experience the claustrum's reboot of consciousness from the inside.
It accounts not-at-all for breakthrough - it makes me wonder if the nature of breakthrough does have some aspect beyond the neuro, or perhaps there's a threshold in which the consciousness is brought down to the level of a single neuronal exchange in order to account for the fact that the "synchronized waves" are no longer available. And here you experience your self moving through the universe-sized network of your own brain. Etc.
