LSD is a highly potent hallucinogen which can profoundly alter consciousness. The exact causal mechanism of this drug is unknown, but much information about its effects on the brain has accumulated over the past few decades. Understanding the causal mechanism behind its action may have positive benefit for therapeutic, pharmacological, and scientific applications. The action of LSD in the nervous system can be approached at phenomenological, neurochemical, and neuroanatomical levels. At the neurochemical level, the action of LSD is thought to involve serotonin and dopamine receptors, as well as glutamate and the expression of the genes c-fos and rac. At the neuroanatomical level, LSD action is thought to be focused in the thalamus, raphe nucleus, cortical pyramidal neurons, as well as numerous other locations.
