Dads will often say that fatherhood changes you – but did you realise those changes happen at a physical, biological level as well as in fathers’ perspectives and values? We often assume that biologically mens’ bodies are unaffected by the arrival of a child. But huge hormonal changes take place at the point of the child’s birth, and research shows that when fathers interact with their children incredible neural activations take place. How do these changes prepare children for the world? And what is fatherhood doing to men’s brains? Dr Pascal Vrticka discusses astonishing research into paternal neural synchrony with Anna Machin and find out how fatherhood changes you more than you could ever imagine.
