the human brain is a constant dialogue

“…the human brain is a constant dialogue between our old 🦎 reptilian 🧠 brain with the spinal cord sticking out at the bottom, which runs our instinctive survival 🧰 mechanisms, and our mammalian neocortex, the new outer layer, which occupies about 70 percent of the volume and is the organ of intelligence.”
