The Neurobiology of Motivational Systems

W HEN WE APPROACH the problem of defining the neurobiological substrate of any psychological function, we inevitably must conclude that virtually all functions are to a greater or lesser extent whole brain involvements. Nevertheless, given functions do involve certain areas more predominantly than do others. Therefore, we will first want to identify those areas most crucial to the systems Dr. Lichtenberg has outlined. It is noteworthy that his clinical approach so closely parallels clearly definable subsystems of the general "motivational" apparatus. It is gratifying when such correlations can be established, and that will be the purpose of this chapter.
