Got a problem - put your electric thinking cap on  Edward de
Bono eat your heart out - scientists at the University of Sydney
have invented actual, as opposed to metaphorical, thinking caps
to stimulate people's brains Doc from Back to the Future Doc
from Back to the Future models his prototype brain stimulation
device.  Scientists have made people better problem solvers by
applying tiny electric currents to their brains.  A gentle
zapping appeared to free people from taking narrow approaches to
cognitive tasks, by stimulating some regions of the brain and
dampening down the activity in others.  Scientists at the
University of Sydney who led the research said the work was a
stepping stone towards a "dream device" that could let people
see the world afresh.  The technique, called transcranial direct
current stimulation (tDCS), sends apparently harmless, minuscule
currents across the brain through conductive pads placed on the
skull.  In the first phase of the study, 60 healthy volunteers
aged 18 to 38 were set
