First, just right off the bat, please pop it out and run it through a spellcheck of some sort. There are a lot of little grammatical errors in the page, and most of them should be quick to fix.
The biggest thing, though, is that there's NO explanation for how this does any of what it says. It's just kinda handwaving that somehow we're now programming completely organic, natural growth with no explanation on what we're doing to make it happen, or why it hasn't been done before.
Outside of that... Who's developing it? Where? And why? Nepleslia already has its enhanced soldiers, Yamatai has its engineered ones, even Lor has an entire genetically guided caste focused on being soldiers. I honestly can't name a nation that has the technology to do something like this, that doesn't also have something better or at least similar.
In terms of the actual effects... How can they control the stimulus dampening? Or for that matter, is it controlled, or is it just inherent, turned on all the time? If it's on all of the time, that can be a HORRIBLY scarring condition, and it's one that occurs naturally. People with it tend to horribly injure themselves repeatedly throughout childhood. It tends to result from little stuff, like not realizing you're pushing into a sharp edge, and the like.
What causes the migraines? Typically, that's a sign of restricted blood vessels in the head, but nothing you've included would trigger that, so far as I can tell.
