Who are we? What defines us? Is it our individual experiences, emotions, and decisions? The interaction of the heart and brain is essential to our ability to make conscious decisions, with the heart sending signals to the brain that influence our feelings and emotions. So, experiences that affect our heartbeats can therefore modify the results of our brain processes, including decision-making. Heart on the Brain is a reflection on what it means to be human, a discussion of the scientific evidence for the heart's influence on the brain, and a guide to listening to both in order to make better decisions and be the person we aim to be.
