Daniel Siegel conceived the expression “interpersonal neurobiology” in his landmark work The Developing Mind. In his later work, Mindsight, he has described nine different domains or functions of the mind and how their integration contributes to robust mental health. Integration, therefore, refers to the growth and maturation of each domain in its ability to do what it is designed to do, while simultaneously linking with other domains. Thus they are in fluid communication with each other.
