Okay since nobody has a clue what I mean I shall give an example for it this once, which if you wish to use the Simian Flu just vote for it.
The Simian Flu works on account of a virus mainly based in the brain. For Neural Enhancement such as the one I am suggesting she is doing currently you would need to allow the Virus to enter Emily's brain and allow it to re-write portions of her DNA, resulting in an improvement to her existing Neural Pathways. That is what I mean by making your explanations sound 'scientific'. Outline the steps you wish to perform, what the virus/bacteria/whatever would do, and the end-goal.
