In their research, Duman and others show that in a series of steps ketamine triggers release of neurotransmitter glutamate, which in turn stimulates growth of synapses. MSG is monosodium glutamate, and there is research to show MSG is toxic -- it's the glutamate that's bad for you, not the sodium. Flooding your body with excess glutamate throws off the brain's delicate balance of this neurotransmitter and leads to excitotoxicity (http://en.wikipedia.org/wiki/Excitotoxicity http://en.wikipedia.org/wiki/Excitotoxicity). The blood-brain barrier protects you from some of it, but the blood-brain barrier is not fully formed in babies, and this is why MSG not allowed in baby food. However, the blood brain barrier can be weakened by any number of reasons in adults, such as when you have a fever. Why would ketamine's release of glutamate be different and good for you in this case?
