Cancer is much like this except it is a genetic mutation in the cells that cause them to become cancerous, the tumor-suppressor is turned off and the cancer continuously replicates because there are no regulatory factors. Its a near impossible, not impossible but difficult.Even if you somehow overcame all of that its highly likely that the human would not survive such a procedure.-I believe you can mutate DNA but by forcing a mutation in the body you only change the DNA in those cells and any future cells made from them,......
In order to get a hereditary change in the brain you would need to know how to change the DNA sequences in the eggs (or the ovaries that produce the eggs), so that the egg with the altered DNA could then be fertilized and grow into a human with a changed brain.
You would need to sequence this growth and its characteristics into the codons without altering things that you didn't want to change. Not only that but its likely the body would simply reject this altered DNA unless you found someway for it to fight the near infinite amount of cells that the human body would deploy to eliminate it and you would have to suppress tumor-suppressor gene to an extent.

I believe you can mutate DNA but by forcing a mutation in the body you only change the DNA in those cells and any future cells made from them, they would have to then be replicated through the Egg (Since it's a female subject) which is a bit far from the brain, and then chosen in the mixing of DNA. So if you can figure out some type of virus or device or even procedure that makes her a carrier and changes the DNA makeup of the reproductive cells then her offspring would likely develop and pass on the mutation, making it like any other hereditary disorder
