Martin Daubney walks away from his position as editor of a renowned porn magazine after becoming a father. With his son, now four years old amongst the confusion by contradictory headlines, and driven by the knowledge that his boy will soon reach the age at which most children first see porn--10 years old--Daubney wants to find some answers. How does pornography effect kids? Where is the evidence? Porn on The Brain takes us through the journey, and Daubney discovers that porn has changed from what he remembers as a teenager--today's porn is extreme, it's free, it's pervasive and only one click away, and Daubney is shocked by the content. Porn on The Brain reviews internationally-renowned neuroscientists, leading therapists and educators who are all concerned about the effects on vulnerable teenage brains today of free and easy access to hardcore pornography. The film includes the shocking results of a specially-commissioned survey of teen porn habits, conducted for the documentary by the University of East London; and collaborates with the University of Cambridge to conduct the first study of its kind, scanning the brains of men who feel they are addicted to porn. When will we acknowledge that there is a problem?
