Phencyclidine is an NMDA receptor antagonist, which means it blocks the effects of glutamate on NMDA receptors. Glutamate is the primary excitatory neurotransmitter in the brain, and its activity is increased in response to phencyclidine treatment. GABA, dopamine, and acetylcholine are all inhibitory neurotransmitters, and their activity is decreased in response to phencyclidine treatment.
