Primitive reflexes live in the brainstem. As the brain matures, the cerebellum and frontal lobes team up to regulate that brainstem and switch those reflexes off, making room for complex, coordinated movement 🧠⚙️ When the cerebellum or frontal cortex are underdeveloped, the brain can’t inhibit those patterns, so the reflexes linger and get in the way of smooth motor control, attention, and learning. Think rooting and palmar grasp. As babies, these automatic patterns help us survive and build ea
