Altered

Robb Jarrett

Curious what really happens when the mind steps outside ordinary waking life? This podcast explores the science, history, and culture of altered states — from psychedelics and plant medicines to meditation, hypnosis, anesthesia, dreaming, sensory deprivation, and everything in between. We dig into the research without the jargon overload, unpack the stories and traditions that shaped these experiences across cultures and centuries, and talk honestly about what people actually encounter when consciousness shifts. No hype, no lectures — just clear, thoughtful conversations about one of the most fascinating (and least understood) parts of being human.New episodes regularly. Come along for the ride.

    What Actually Happens When You Die? (The Final Minutes)

    Examine the physiology of near-death experiences and how the brain reacts when oxygen supply is abruptly cut off. We explore the critical window of brain function when the heart stops, causing rapid depletion of fuel and oxygen. This analysis investigates the biological mechanisms at play during the moments of clinical death, moving past speculation to look at the high energy demands that sustain our cognitive processes. It is for those interested in the physiological reality of the dying process. By observing the relationship between cerebral metabolism and the cessation of vital signs, we can better grasp the limits of human consciousness. We break down the clinical sequence of events that occur as neural activity falters, providing a clearer picture of what happens at the boundary of life. This inquiry bridges the gap between medical reality and the subjective accounts often reported during these critical moments. Subscribe for weekly explorations of the human mind, and comment below on your perspective regarding the nature of the near-death experience.

    Can We Prove What Consciousness Really Is?

    Can large language models ever achieve consciousness? We explore the biological binding problem and the nature of subjective experience. This video examines how our brains integrate sensory information to create a unified sense of self. By comparing neural networks to artificial intelligence, we analyze whether machine learning systems might eventually simulate human awareness or if there is a fundamental gap that technology cannot bridge. We look at the latest theories regarding brain function and the broader cosmos to determine if consciousness is a biological accident or a universal property. Understanding the binding problem is essential for anyone interested in the intersection of neuroscience and computer science. We break down the complex relationship between neural processing and the emergence of subjective experience, providing clarity on where current research stands. By the end of this analysis, you will have a better framework for evaluating claims about machine sentience. Subscribe for weekly science breakdowns and comment below with your thoughts on whether AI will ever truly be conscious.
