It sounds to me like they were studying the effects of chemistry on the developing brain, and were measuring the effects altered chemistry has on the electrical conduction processes within the developing brain of zebrafish.
If they could come up with a cure for PTSD, that would be awesome.
That all aside, I wonder what a jury rendering would be if it turns out that this guy was under a brain altering experiment?
If it turns out that that’s the case, If I were on a jury with only the facts we’ve been presented with thus far, I’d have to award him life in the nut house. There’s no telling if he would ever be normal again, and I wouldn’t want him exposed to society again.
So... maybe instead of just the Zebrafish, he tried it out on himself.
