O que acontece com o cérebro durante o ritual de ayahuasca?

What happens in your brain during an Ayahuasca ceremony? Neuroscience reveals the unique mechanism behind this ancient Amazonian brew. What happens in your brain during an Ayahuasca ritual? Unlike any other psychoactive substance, Ayahuasca combines DMT with MAO inhibitors (β-carbolines), creating a prolonged experience that simultaneously activates 5-HT2A and sigma-1 receptors and the limbic system—modulating emotional processing and brain connectivity. Neuroimaging studies (fMRI and EEG) show reduced activity in the default mode network—associated with the ego and rumination—and increased communication between regions that do not normally connect. It is this transient hyperconnectivity that explains the visions, the reorganization of emotional memories, and the feeling of unity. In this video, Professor Vanessa Kaniak explains the neurobiological mechanism behind the Ayahuasca ritual — from the activated receptors to changes in brain connectivity — based on current science, without speculation. #ayahuasca #neuroscience #brain ______________________________________________________ 🎥 Content about: • Neuroscience applied to everyday life • Human behavior • Beliefs and personal transformation • Emotional intelligence • Awareness and self-knowledge • Near-Death Experiences (NDEs) • Documentaries and investigations about the human mind ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔬 ABOUT THIS CHANNEL Vanessa Kaniak investigates the human experience at the interface between neuroscience, consciousness, and behavior. On this channel, you'll find documentaries, analyses, and reflections on the mind, perception, identity, beliefs, emotional patterns, and brain function, presented with depth, rigor, and accessible language. The aim is to understand how the brain shapes the way we feel and perceive reality, and to what extent science has already been able to investigate consciousness, behavior, and borderline human experiences, such as near-death experiences and expanded states of perception. Vanessa Kaniak is a professor, holds a postgraduate degree in Neuroscience and Behavior, is a lawyer, has a Master's degree in Applied Social Sciences, and facilitates ayahuasca medicine experiences in Brazil. Her research integrates science, behavior, and profound dimensions of human experience. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📌 CONTACT ✉️ [email protected] 📷 Instagram: @prof.vanessakaniak ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ #Neuroscience #Consciousness #Behavior
