Ketamine was invented in 1962 as a very effective anesthetic for routine surgery. It is blocks the neurotransmitter molecule glutamate from its NMDA receptor in brain neurons, and affects primarily the memory center in the hippocampal region of the brain, along with the prefrontal cortex abstract thought center.
