The Imprinted Brain sets out a radical new theory of the mind and mental illness based on the recent discovery of genomic imprinting. Imprinted genes are those from one parent that, in that parent's interest, are expressed in an offspring rather than the diametrically opposed genes from the other parent. For example, a higher birth weight may represent the dominance of the father's genes in leading to a healthy child, whereas a lower birth weight is beneficial to the mother's immediate wellbeing, and the imprint of the mother's genes will result in a smaller baby. According to this view, a win for the father's genes may result in autism, whereas one for the mother's may result in psychosis. A state of equilibrium - normality - is the most likely outcome, with a no-win situation of balanced expression. Imprinted genes typically produce symptoms that are opposites of each other, and the author uses psychiatric case material to show how many of the symptoms of psychosis can be shown to be the mental mirror-images of those of autism.

Combining psychiatry with insights from modern genetics and cognitive science, Christopher Badcock explains the fascinating imprinted brain theory to the reader in a thorough but accessible way. This new theory casts some intriguing new light on other topics as diverse as the nature of genius, the appeal of detective fiction, and the successes - and failures - of psychoanalysis.

This thought-provoking book is a must-read for anyone with an interest in autism, psychiatry, cognitive science or psychology in general.

Christopher Badcock was educated at Maidstone Grammar School and The London School of Economics, where he graduated with a First in Sociology and Social Anthropology. Seeking to find a sound evolutionary, genetic, and neuro-scientific basis for psychoanalysis, he realized that research into autism completely discredited Freud but suggested a completely new basis for understanding the mind and mental illness. With the help of the leading Canadian bio-scientist, Bernard Crespi, he was eventually able to consolidate these insights into the imprinted brain theory outlined here and published a number of co-authored papers on the subject. Christopher Badcock is the author of a dozen books, and today teaches courses on evolutionary psychology, genetics, and sociobiology at the London School of Economics. He lives in London.
