Your research explores how our brain, mind and behaviour are linked. What drives your interest in that? The early 20th century was the era of physics and the second half was era of biology and amazing genetics. Now the 21st century is the era of the mind. We are escaping the curse of biological determinism, that over-emphasis on âhardwareâ. We are rediscovering the software, the role that the mind plays in our bodies and behaviour. What have you seen happen in your area of research? When I studied psychology, I was brought up to believe that we lost brain cells after childhood and the central nervous system could never regenerate. The big change since then is the discovery that we can form new connections between brain cells in adulthood, and even grow new neurons.
