Limbic System is involved in the Expression of Instinct and Mood

Limbic system is a group of regions in the brain that is involved in the expression and control of mood and instinct and plays a major role in long-term memory. The limbic system includes the hippocampus and the hypothalamus. It functions as the brain’s ‘emotional system’. The hippocampus and the temporal lobe are major sites for long-term memory storage, the former receiving inputs from the inferior temporal region of the cortex. Its efferent pathway is the fornix, which in turn provides input to the hypothalamus. The activities of the body that are governed are those concerned with self preservation (e.g. searching for food, fighting) and preservation of the species (e.g. reproduction and the care of offspring), the expression of fear, rage, and pleasure, and the establishment of memory patterns.
