REBUS

Furthermore, our default mode network, DMN, our brain's personal narrative generator and ego controller, acts as a central hub for self-reflection and cognitive control.

Under neuroscientist Robin Carhart-Harris's REBUS model, Relaxed Beliefs Under Psychedelics, published in 2019, relaxing top-down brain filtering floods waking awareness with unconstrained sensory and cognitive data.

However, this is where mainstream neuroscience and filter theory part ways.

Neuroscience agrees that the brain filters information, but it asserts that it is filtering internal neural noise and raw sensory inputs, the generator view, rather than an external universal consciousness field, the receiver view.

Right now, psychedelics have been getting very, very popular, both in culture, but also now with the more acceptance of their medical use.

But all of this renewed interest has been with a very specific and narrow scope, which is very much influenced by neuroscience with a whole The Rebus model, predictive processing, all these types of frameworks are very, very brain focused, almost to the point where it's almost the only thing that seems acceptable to talk about within the realm of psychedelics.

So philosophy of psychedelics, like we were talking about before, just a podcast is a very niche thing.

Very few people are working on it.

Like this.

The REBUS model, that's R-E-B-U-S, which stands for Relaxed Beliefs Under Psychedelics, yeah, they got a little creative with that acronym, suggests that psychedelics provide relief from top-down instructional systems that are rigidly drafted from the brain's predictive habits, especially following trauma.

The brain, with its heightened peak alpha frequencies in PTSD, stubbornly believes that it knows what is happening next, what is happening presently, without real evidence as a common outcome of traumatic stress, the black and white thinking and omnipotence problems.

The brain, one might say, assumes that the worst is real and enforces behaviors in respect to those negative expectations, drastically limiting the experience of the individual.
