World-leading neuroscientist and psychologist Dr Ruth Feldman has spent decades studying the intricacies of our social interactions. Her lab has shown that humans bond so deeply that we alter one another's biology - our brain waves align, our hearts beat the same rhythm, and hormones are released in tandem. This is biobehavioural synchrony.

Drawing on decades of pioneering research, Synchronized lays out the profound impact synchrony has on human life, from birth to old age, by following the stories of parents and children, lovers, and friends. We see the call and response between mothers and newborns, meet married couples in crisis, trace the biological imprint of loss and trauma, and learn how synchrony enriches and repairs our relationships, builds resilience and even improves our health.

Both rigorous and deeply humane, Synchronized reveals the magic of synchrony at work in our lives and touches the very basis of what makes us human.
