OK, some of this is nonsense, but it at least it is nonsense with
McFadden's work can be found through
Stapp can be found at
I recall Roger Sperry describing in class some 45 years ago his
experiments showing how general electric fields could not be
responsible for "gestalt" phenomena -- he shortcircuited brain regions
with tantalum wires and isolated brain regions with mica insulators
but neither intervention had any effect on cortical function.
The speculations of many physicists over the past century or more
about brain function have not yet led to breakthroughs in our
understanding. Will one of these three prove to be the exception?
