The existence of SELFs is independent of the physical systems they can enform. Because SELFs exist in spacetime, whereas physical systems are confined to three-space, the observable behaviors of SELFs depend on their ability to organize physical systems in ways that alter their behavior in spacetime. Many resulting phenomena are atemporal and nonlocal. This aspect implies the rudiments of ordinary human mentality, as well as unusual expressions of mentality such as multiple personality disorder. These characteristics of QM and psi phenomena reflect the discontinuity in three-space and continuity in spacetime of SELFs.
Neurons conform as ensembles to SELFs at many levels of organization and complexity.
Mind and matter don't interact. Enformy, therefore mental events, interacts profoundly with matter, just as energy interacts profoundly with matter. Mind equals brain. Mind and brain are disjoint, therefore non-equivalent, sets of perceptions. Brain operations uni-directionally cause mental activity.
