1. John Nash, not George. 2. So far as I can tell, Nash was never treated with electroconvulsive therapy. 3. ECT has scarcely anything in common with tDCS. 4.

I would be more inclined to blame the major mental illness for any falloff in the quantity or quality of his output, rather than the treatment he received for it.
