ABSTRACT
The limbic system is a series of centres collectively involved in preservation of the individual (i.e. self-preservation) and preservation of the species. It governs behaviour essential to the survival of the individual, ensuring, for example, that we seek food or respond to threats, and also promotes reproductive behaviour (see Chapter 1) to ensure survival of the species. The major components of the limbic system (Figure 9.1) are the amygdala; the mammillary bodies of the hypothalamus; the anterior and dorsal nuclei of the thalamus; several deep nuclei and the septal area. The orbitofrontal cortex of the cerebrum, several other areas of the cortex, such as the hippocampus; the parahippocampal gyrus and parts of the temporal lobe are together known as the limbic cortex because of their close association with the functions of the limbic system.
