The teaching brain is a new concept that mirrors the complex, dynamic, and context‐dependent nature of the learning brain. In this article, I use the structure of the human nervous system and its sensing, processing, and responding components as a framework for a re‐conceptualized teaching system. This teaching system is capable of responses on an instinctual level (e.g., spinal cord teaching) as well as higher order student‐centered teaching and even more complex teaching brain teaching. At the most complex level the teacher and student engage in a synchronistic teaching flow that achieves the optimal teaching and learning experience.
