Functional Neuroanatomy of the Brain

Understanding the relationship between brain structure and function, and particularly how this relationship becomes disturbed in the mentally ill, is one of the major challenges to clinical and experimental neuroscientists. The brain may be described in terms of its general structure and key anatomical areas. It may also be described in terms of the cellular or subcellular structure of the different types of cells that constitute the brain. Finally it may be considered in terms of its functional importance in memory, consciousness and control of bodily functions. However the brain is described, each level of organization is essentially linked to another level of organization. Conventionally, neuroscientists have concentrated on the structural aspects of the brain and its cellular components while psychologists and psychiatrists have concentrated on the more functional aspects such as consciousness, thought processing and emotion. With the advent of sophisticated imaging methods and the introduction of novel drugs that combine therapeutic efficacy with subcellular specificity of action, it is now possible to show how all the levels of brain structure and function are interlinked. This will be illustrated by presenting an overview of brain structure and function and the reader is referred to the key references for further details of neuroanatomy. The principal regions of the human brain which are important in psychiatry and neurology are shown in Figure 1.1.
