Please see my link " Intelligence vs Consciousness" mentioned above.
I postulate that the links roughly parallel to the arcuate fasciculus couple the motor planning stages at an early motor planning level to the later sensory stages in the parietal lobe.
In the explanation, it describes a high-level loop that is the basic consciousness process.
This process is at a level before being gated to action.
So in a sense - the motor planning stages are driving the internal states in the brain.
This concept is inspired by the “The Global Neuronal Workspace Model” described here:
