In "Neuropsychedelia," Nicolas Langlitz embarks on a mesmerizing journey into the heart of psychedelic science's resurgence, navigating the complex interplay between neuroscience, spirituality, and society. With the 1990s hailed as the "Decade of the Brain," Langlitz meticulously chronicles how a new cadre of researchers, emerging from the ashes of the 1960s countercultural and establishment clashes, seized this neuroscientific fervor to reincorporate psychedelics into mainstream scientific discourse and investigation. Through his immersive anthropological fieldwork in two pivotal labs—a human laboratory in Switzerland and an animal laboratory in California—Langlitz unveils the transnational revival spearheaded by American psychedelic culture's intrigue with LSD's Swiss origins, offering an unprecedented glimpse into the laboratories that have been instrumental in this scientific renaissance. "Neuropsychedelia" not only explores the scientific endeavor to harness hallucinogens for modeling psychoses and eliciting spiritual experiences in controlled settings but also delves deep into the philosophical and existential questions that arise at the intersection of modern materialism and the mystical. Langlitz, with a keen anthropological eye and philosophical depth, examines the struggles and aspirations of those at the forefront of this revival—scientists, researchers, and the anthropologist himself—as they navigate the delicate balance between the empirical demands of late-modern science and the human yearning for transcendental experiences. This book is a compelling narrative that challenges our understanding of consciousness, spirituality, and the potential of psychedelics to unlock new dimensions of the human experience.
