Another user, pcuser, has posted an article which states that the same neurotransmitter, GABA, might be implicated in autism.
This might be significant. Who knows? Maybe in the future, they could make use of this research in the actual treatment of some forms of autism which is caused by the actions of this neurotransmitter.
I do wish they would specify what type of autism they were studying.
Thanks, ZombieBride!
