This book has become a recognized world bestseller. Richard Davidson is one of today's leading brain researchers, and his approach to personality and human emotion is truly innovative. Each personality is a unique composition of six basic emotional “styles” in special proportions, therefore a person’s psychotype is as individual as his fingerprints. Each emotional style is associated with certain chemical processes in the brain, and thanks to this fact, we can manage and develop our brain by controlling one or another emotional style. Using this technique, you can not only develop as a person, but also treat depression, autism and other mental illnesses. In this book, Davidson and Begley describe their approach in detail and in an accessible way, so you can use it yourself.
