Please note: This is a companion version & not the original book. Book Preview: #1 We tend to separate mental health from physical health. But what we actually know about the brain is that it resides in our gut. It takes in tons of information and makes decisions before we are even aware that a decision needs to be made.#2 The prefrontal cortex, the front part of your brain, is in charge of executive functioning, which includes problem-solving, goal-oriented behaviors, and managing social interactions according to expectations of what is appropriate.#3 The prefrontal cortex is the part of the brain that is responsible for thinking and making decisions. It is highly connected to the rest of the brain, and it receives feedback from the brainstem arousal systems.#4 The limbic system, which is the middle part of the brain, stores memories related to emotions. The amygdala, which is part of the limbic system, stores event-based memories. The brainstem is the final part of the brain, and it controls basic functions like breathing and heart rate.
