Question

Quizplus · Accepted Answer

Hallucinogens such as LSD and mescaline interact with specific serotonin receptor sites in the brain, leading to altered sensory experiences and hallucinations. Psilocybin is a specific hallucinogenic compound found in certain mushrooms, but it acts primarily as a serotonin agonist. Melatonin is a hormone involved in regulating sleep-wake cycles, not hallucinations. Phencyclidine (PCP) is a dissociative drug that can cause hallucinations, but it acts on different types of receptors than serotonin. Norepinephrine is a neurotransmitter involved in arousal and stress responses, but it is not directly implicated in hallucinations.
