The way you perceive the world, plan, make decisions and communicate your thoughts and feelings depends on the function and hierarchical arrangement of cortical modules.  The ability to both provide adaptive responses to our ever-changing environment and to pursue a useful role in society is the most important problem faced by present day neuroscientists. In essence, the workings of cortical modules define the nature of our soul, making each of us who we are. This book provides a breath-taking view of different perspectives by world renowned authorities as to the workings of these cortical modules both in the normal state and in mental disorders.
