In Heavens name WHY?
Glutamate activates NMDA receptors.
Neuronal receptors are proteins that float around in neurons' cell membranes. NMDA receptors are only about 1% of cerebral neuronal receptors but they are widely distributed throughout the entire brain. They play a part in long-term potentiation, which is believed to be one of the mechanisms of learning & memory
. Why on EARTH would you want to neutralize that?
