In this episode, researcher Mikael Palner reveals the surprising science behind the psychedelic renaissance, how compounds like psilocybin create a "window of opportunity" to rewire the brain for creativity and healing, and the unspoken dangers of "hero doses," emotional addiction, and the shocking risks of long-term microdosing.

Dr. Mikael Palner is a neuroscientist with over 15 years of experience in psychedelic research and advanced preclinical brain imaging. He leads his own research team investigating how psychedelic drugs impact neuronal circuits in the brain and has been awarded prestigious grants from the Danish Independent Research Foundation and the Danish Innovation Fund for his work.

He explains:

◻️️ The real reason psychedelics were banned for decades and why they're exploding in popularity now.

◻️ The surprising scientific difference between DMT, psilocybin (mushrooms), and LSD.

◻️ How psychedelics create a temporary "window of plasticity" to permanently rewire your brain and habits.

◻️ The unspoken truth about addiction: the difference between physical dependency and the "emotional addiction" many users experience.

◻️ Why a "hero dose" can be a dangerous mistake and how a proper therapeutic dose is determined.

◻️ The chilling risk that psychedelics can create traumatic memories of events that never actually happened.

◻️ The long-term dangers of microdosing and why being in a constant state of brain plasticity is like having a "teenager brain".

◻️ The future of mental health: how scientists are trying to create non-psychedelic versions of these compounds to treat anxiety.

◻️Why anxiety may be the real epidemic of our time—and the top five tools anyone can use to manage it.
