The field of psychedelics research has exploded in recent years, as scientists dig deeper into the neuroscience and pharmacology of hallucinogens and how their unique properties can be harnessed to understand and treat depression, anxiety, post-traumatic stress disorder, Alzheimer’s disease, dementia, and neurodegenerative diseases. Remarkably, the human body produces its own endogenous psychedelics, the reasons for which have implications for understanding the ordinary and extraordinary states of human consciousness, from creativity and dreaming to near death experiences. 

In this episode, Iris Kulbatski from The Scientist’s Creative Services Team spoke with Steven Barker, a professor emeritus at Louisiana State University to learn more about the human body’s ability to produce hallucinogenic compounds and their roles in physiological processes.
