A sense of pleasure generated by the brain's hedonic neural systems is fundamental to daily life, and indeed has been essential to the evolution and survival of humans and most animals, say Morten Kringelbach and Kent Berridge, editors of Pleasures of the Brain. The rewards we experience through sensations such as food, sex and social interaction are driving forces necessary to maintain life, they argue.
Pleasures of the Brain, to be published by Oxford University Press on 1 October 2009 is the first book of its kind in decades on the neurobiology of pleasure. Until recently, pleasures have been regarded as too subjective to study scientifically and have remained in the domain of psychology. But since the late 1990s it has become apparent that both conscious and unconscious pleasures of rewards are central to affective neuroscience and well-being. Conversely, a lack of it - anhedonia - is a major feature of mental illness.
Kringlebach, an Oxford University neuroscientist, and Berridge, a psychologist from the University of Michigan, tackle the subject by first asking scholarly experts a series of fundamental questions on the role of pleasure in psychology and in the brain. The experts provide answers to the questions they feel most passionately about, thus revealing the frank and sometimes disparate views that might lead to the best concepts in this newly emerging field of hedonic science.
The rest of the book is divided into three main sections: animal pleasures, human pleasures and clinical applications, with contributions from over 30 European and American experts.
Animal pleasures starts with an overview of research into the hedonic hotspots of the rodent brain that generate a basic sensory pleasure, describes the associated brain regions and concludes with the neuroethology of research into pleasure in non-human primates.
