It's disappointing to me that they don't take advantage of these volunteers to repeat the 
Grey Walter experiment.  ISTM that it offers a lot more precision and avoids questions of 
timing in reporting.


Anyway it's another indication that consciousness may be overrated.

Re: Brain imaging spots our abstract choices before we do

What we need now is 20 years of serious neuroscience, not more 
speculation about the handful of studies that have been done so far, he 
says.

Too bad that we have no freedom to decide whether to pursue serious 
neuroscience instead of more speculation...it's all up to neurons, and 
there are ions that flow through membranes. As impotent spectators to the 
magic of calcium and potassium, we can only sit back and enjoy the view 
from beneath their puppet strings.

Unfortunately they have learned nothing from Libet's mistakes. I can't 
understand how intelligent scientists could continue to conflate free will 
with the awareness of free will and the reporting of the awareness of free 
will - clearly three different sub-personal capabilities when fragmented in 
a contrived laboratory experiment. How could anyone who is serious about 
consciousness think that repeating a conditioned, meaningless reaction to 
some stimulus would yield good insight into the motivations and capacities 
of the human psyche?
