The field of neurobiology is helping to provide a more in- depth understanding of the human brain and the mind. The functions of the middle prefrontal cortex of the brain, described by Daniel Siegel in The Mindful Brain, include bodily regulation (balancing the sympathetic and parasympathetic nervous systems), attuned communication (coordinating input from your mind with another’s), emotional balance, response flexibility (the ability to pause before action—the root of the STOP tool), empathy (the root of the Transpose tool), insight (self- knowing awareness), fear modulation, intuition (processing deep ways of knowing), and morality (what is best for the whole and not just for oneself). These brain centers have been observed to maintain their ability to grow until the very end of life. The Inner Game focuses on the many built- in resources we have as hardware and offers tools to increase access to them. Scientific studies are confirming the existence of these resources, as well as our ability to enhance our access to them.
