LSD Neuroscience - David E. Nichols

Neuroscience research on hallucinogens focuses on receptor activity, particularly 5-HT2A and 5-HT2C. LSD functions as a psychedelic through these targets, which are highly expressed in brain areas related to consciousness, perception, and abstract thought. Clinical research has seen a massive surge, revealing complex signaling pathways where drugs bind to receptors, altering cell function beyond simple activation. While research chemicals like 2C-B and various novel substances pose safety risks, LSD and psilocybin demonstrate low toxicity profiles. Animal studies, such as the two-lever drug discrimination paradigm, are crucial for preclinical work but cannot model the totality of human experience.
