What makes you the way you are and what makes each of us different from everyone else? Join Kevin Mitchell as he traces human diversity and individual differences to their deepest level: in the wiring of our brains. Guiding us through important new research, including his own ground-breaking work, he explains how variations in the way our brains develop before birth strongly influence our psychology and behaviour throughout our lives, shaping our personality, intelligence, sexuality, and even the way we perceive the world.
