Descartes like Plato believed the immaterial mind and physical body were separate but communicated in the brain at the pineal gland. Animal spirits moved from the brain to act on the muscles and experiences lead the nerves to open up “pores” in the brain to form memories. Descartes was right about the nerves connecting the inside and the outside worlds but had no notion of how these nerves functioned.
