As neuroscientists expand definitions of the mind beyond a direct corollary with the organic brain, Hebbian theory that brain cells that "fire together, wire together" has gotten an important update from psychosociobiologist Louis Cozolino: it turns out that minds that fire together, wire together also.
This social brain — the mind — helps us to regulate each other's metabolic activations, emotions, and behavior, seeking sociostasis (or social equilibrium) through the social synapse. The social synapse is defined by Cozolino as the exchange of energy across the gap from one person to another (as with the neurosynaptic gap from one neuron to another). The social synapse binds us into larger organisms like families, tribes, societies, and the human species and acts as a high-speed information linkup that runs on ongoing physiological and emotional synchrony.
Cozolino has authored and co-authored multiple texts, helping pioneer a new way of joining psychotherapy practice, education, and neuroscience. Here are a few that stand out: The Neuroscience of Psychotherapy: Healing the Social Brain; The Social Neuroscience of Education: Optimizing Attachment and Learning in the Classroom; and The Neuroscience of Human Relationships: Attachment and the Developing Social Brain.
