Ep. 151: Neuroscience, Memory and Psychedelics (feat. Manoj Doss PhD)
Today on the Mushroom Hour Podcast we are blessed to speak with Manoj Doss. Manoj is a cognitive neuropsychopharmacologist at the Center for Psychedelic and Consciousness Research at Johns Hopkins University. His research is at the intersection of cognitive neuroscience and neuropsychopharmacology with focuses on episodic memory and hallucinogenic drugs. Manoj utilizes complex cognitive paradigms, brain imaging, and computational modelling to explore what makes psychedelics unique compared to other classes of psychoactive drugs, both in terms of basic drug effects and mechanisms for treating clinical populations. Although Manoj is optimistic that psychedelics will soon have a place in psychiatry, he remains cautious of exaggerated claims and negligence to potential downsides, something he terms 'psychedelic myopia’.
