🧠 7 Circuits of Brain Function – 1st Circuit The video explains the first brain circuit, the Reptilian/Bio‑Survival Circuit focusing on its evolutionary roots, survival‑based behaviour, and link to the root and sacral energy centres. Key Points . Reptilian Brain - Oldest part of the brain - Humans retain reptilian traits - Embryos pass through a reptile‑like stage 2. Reptilian Consciousness - Driven by safety vs. danger - Individualistic and territorial - Only gathers for mating or defence 3. Bio‑Survival Circuit - Governs basic survival and threat response - One‑direction perception: - Forward = safety - Backward = danger - First circuit activated in infants 4. Energy Centres - Linked to root + sacral energy seats - Many remain stuck in survival mode 5. Evolving Beyond Survival - Survival mode limits growth - Aim is to move toward thriving and higher development
