The problem with this neuro-centric position, is the general problem in almost all of the biological (or even All, for that matter) sciences. The issue of 'compartmentalization' and over-simplification of "units" (like the organs) of the body, as opposed to seeing the Body as a Whole.
Science 'needs' to think in terms of separate and discrete functions, and therefore separate and discrete functionality. 'The Brain is where thinking happens. All other beliefs are "pseudoscience."'
This negates that the Body as a whole, needs to have all of those 'separate' organs and functions... Well, in order to function. It allows science to 'study' the discrete 'parts,' but then can't see the 'inter-functionality' as the Whole.
The same goes for separating the "physical" body, from the "electrical" one. It makes it 'too damn hard' to study the Whole as a Whole, once again, negating higher levels of "functionality.
In other words... Science (or some scientists) are seeing that there are no 'discrete' organs or functions, and that our previous 'version' of "What is The Body" is lacking in cohesion of study.
We are the sum of our parts. And there are levels of 'functionality' that were considered 'heretical' before now. Such as the inter-relating of the Quantum level functions, with the 'corporeal' functions.
We are now reaching the point where (to use a Buddhist koan), "All Points are One Point." There is Unity and higher levels to be found that are not part of the Newtonian mechanical model to which Science has been chained to for centuries.
We are entering the era of understanding on the "meta" inter-related level, instead of the purely mechanical 'outdated' modality.
Ready for a quantum leap in understanding? The Body as a Cognitive Whole, with 'consciousness' and 'memory' on the cellular level. Our Bodies as the 'CPU' being able to 'download' on the quantum level.
Yeah. I know. Crazy, right?
