MODULE 13 - INTRODUCTION
The limbic system is concerned with: 1) regulating the emotional aspects of behavior, 2 laying down new memories and, 3) regulating the autonomic and neuroendocrine systems. It is also the part of the brain that directly receives olfactory information. Thus it is no accident that odors can be so effective in eliciting emotional responses and can also trigger memories of past events. This topic is clearly the most complex one we take up in this course. The problem is that countless structures are considered part of the limbic system, each one tends to be connected to most of the others - but we have only a vague idea of what the structures and pathways do. It is a region of the brain that is of enormous interest to people concerned with understanding human behavior and one where each week brings new findings.
