There is a electronic brain device currently used by the blind.
Electrode stimulate the brain to produce visual perception. A major
disadvanted is the heat [generated by electrons flowing against
resistance] damage brain tissue eventually rendering this technique
useless. Burnt tissue is dead and does not respond to excitation of
any type. I am thinking of a device using electrical stimulation w/out
generating a denaturing amount of heat.
