It's my understanding that the neurotransmitter GABA is basically the brakes for all other neurotransmitters. The thing that makes most anxiety meds work and that keeps us from having seizures (granted too much can do the same). What else does it do? I have read in zebrafish the inhibition of gaba seems to initiate the regeneration process of their retinas, and in humans it may do the same for the pancreas. What else is it involved in?
