This book presents cutting edge research on the basic neurobiology of parental behavior as it relates to behavioral disorders, including postpartum depression, anxiety, and inadequate parental bonding to infants. Internationally recognized basic and clinical researchers present new research findings in humans and animals that elucidate the roles of the brain, physiological state, genes and environment in maternal and paternal care. By bridging the gap between basic and clinical research, new understandings of how the biology of the brain and the reproductive state of the parent impact their mental health and the successful rearing of young emerge.
