Coordination

Coordination seems to be related to the link between the basal ganglia and the cerebellum.  The cerebellum sends some kinds of motor instructions and the basal ganglia reviews the results to see how accurate the output was relative to what was expected.

Of course, the motor impulses are planned and sent from the frontal lobe, back from the prefrontal cortex to the central sulcus (the split between the front and the back of the brain, running through Cz.)  So, a very slow frontal lobe might well be expected not to do a terrific job of planning and putting together clear orders for muscular activity–especially more complex activity.

I would certainly try some frontal lobe slow-wave squishing.  I would also try (if beta is not already pretty high) Cz beta up and theta down, since there are good connections between Cz and the Basal Ganglia.
