In this article Tortora, a dance therapist, interviews Myron Hofer, director of the Sackler Institute for Developmental Psychobiology, Columbia University. Dr. Hofer has spent decades studying how the mother's behaviors and actions shape and regulate the physiological, neurophysiological, and psychological functioning of her babies--specifically, her baby's brain and behavior. In the interview, Hofer argues that we need to learn more about the effects of sensorimotor stimulation to areas of the brain that regulate emotional development, language development, and other kinds of development.
