On the surface, the idea itself isn't fleshed out enough to be interesting. A bad thing happens and then a good thing happens, making those things a coma and "sudden gain of skills" is not something that catches my eye.
There are a thousand ways to tell a story or describe the effect that would be interesting, but the hook is too vague for me to say "I like it", because half of my brain's going "that's boringly generic" and the other half's going "here's all these ways to flesh it out". But while the second half is interesting, the core idea is not without more flesh to it.
I think you should make it more specific, unless this is literally it. Questions: Does everyone come out of the coma? Are the talents always "conventionally valuable, or do you get stuff like "murder" and "artistic tripping"?
I also think studying the brain waves doesn't explain "how this happened" just how their minds work- it's worthwhile for checking for side effects, but.
If this idea is exactly what it seems: Everyone enters, gets a free coma, gets a free talent, good to go- it's both boring and startlingly benevolent without catch or plot. (unless the plot is "the foundation can't trust a good thing", in which case you need to know that's the plot going into writing.)
