You don't indicate what degree of knowledge or experience you have
with neurophysiology.  But from the way the proposal is stated, I
suggest that you start with a laboratory course in neurobiology.  You
need to understand "the language the visual cortex can understand",
exactly what the role of "negative neuronal ions" (chloride?) really
is, and just how your electrons can exert an effect.  It really is not
clear why you emphasize FSK (frequency shift keying).  Frankly, it
makes absolutely no different to the brain what the internal
representation your digital circuitry uses -- a system using Cobol and
binary coded decimal numbers should work as effectively as anything
else, provided the design is proper.

Note: the laboratory nature of the course is essential.  You have to
understand just what is involved in the reality of neurophysiology.

After that, go into a graduate program in neurobiology or
bioengineering or whatever in some institution that is involved in
visual prosthesis and get attached to a research group as a grad
research assistant.  Then, after some post-doc work in the field, you
will really be in a position to put your ideas (which might change
just a tad from the experience) to real use.
