In the past five years, mainstream media has been weaving in experimental methods from bleeding edge psychology and neurology. For at least the past century, memory implantation and other mental manipulation is a classic science fiction plot mechanic. We see it in Eternal Sunshine of the Spotless Mind, where memories can be erased, something I would never want to do.
To produce spiritual states of mind, would there be certain neuroanatomical objectives or goals for invoking them? If you control your mind, your motor faculties, your cognitive patterns, aren't you influencing electrical and energetic flows within your body, spine and brain? So, if you understand your brain as a computer with complex, biological transistors, then changing the electrical and energetic flows, globally, regionally and circuituitously absolutely has an effect on how they regulate themselves. Further, this is a discussion of neuroanatomy as it relates to spirituality in general, with a strong focus on Buddhist meditation. Christianity and other religious traditions have practices which can evoke similar and potentially identical spiritual states of mind. Some kinds of prayer, especially when extended, force you to open your heart and surrender yourself and your mind to God.
This categorical coherence looks for higher level patterns. It could identify the presence of diseases previously unknown, not because it's matching against a list of diseases and their progressions, but because it's identified unknown patterns of neurodegeneration in a patient. In addition to unknown disease progression, this could also identify the combination of drug-induced neurological damage or damage induced by the combination of diseases.
