The limbic system is the collective name for structures in the human brain The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a mammal with an equivalent body size. Most of the expansion comes from the cerebral cortex, a convoluted layer of involved in emotion An emotion is a mental and physiological state associated with a wide variety of feelings, thoughts, and behavior. Emotions are subjective experiences, or experienced from an individual point of view. Emotion is often associated with mood, temperament, personality, and disposition. The English word 'emotion' is derived from the French word é, motivation, and emotional association with memory In psychology, memory is an organism's mental ability to store, retain and recall information. Traditional studies of memory began in the fields of philosophy, including techniques of artificially enhancing the memory. The late nineteenth and early twentieth century put memory within the paradigms of cognitive psychology. In recent decades, it has.
The limbic system operates by influencing the endocrine system The endocrine system is a system of glands that involve the release of extracellular signaling molecules known as hormones. The endocrine system is instrumental in regulating metabolism, growth, development and puberty, and tissue function and also plays a part in determining mood. The field of study that deals with disorders of endocrine glands and the autonomic nervous system The autonomic nervous system is the part of the peripheral nervous system that acts as a control system functioning largely below the level of consciousness, and controls visceral functions. The ANS affects heart rate, digestion, respiration rate, salivation, perspiration, diameter of the pupils, micturition (urination), and sexual arousal.

- Dentate gyrus The dentate gyrus is part of the hippocampal formation. It is thought to contribute to new memories as well as other functional roles. It is notable as being one of a select few brain structures currently known to have high rates of neurogenesis in adult humans,
- Limbic lobe The limbic lobe is a portion of the brain associated with functions such as olfaction and emotion. It contains parts of other lobes, including the frontal, parietal, and temporal
- Septum pellucidum The septum pellucidum is a thin, triangular, vertical membrane separating the lateral ventricles of the brain. It separates the anterior horn of the left and right lateral ventricles. It runs as a sheet from the corpus callosum down to the fornix. When the hemispheres are cut apart, the septum remains on one hemisphere, usually the left. The
- Subiculum The subiculum is the most inferior component of the hippocampal formation. It lies between the entorhinal cortex and the CA1 subfield of the hippocampus proper
- Alveus of the hippocampus The alveus of the hippocampus borders the wall of the lateral ventricle and is composed of white, myelinated fibers. The alveus arises from cell bodies in the subiculum and hippocampus, and eventually merges with the fimbria of the hippocampus. The fimbria goes on to become the fornix. These structures are part of the limbic system
- Perforant path In the brain, the perforant pathway provides a connectional route from the entorhinal cortex to all fields of the hippocampal formation, including the dentate gyrus, all CA fields, and the subiculum. Though it arises mainly from entorhinal layers II and III, it comprises a smaller component that originates in deep layers V and VI. There is a major

- Paraterminal gyrus The paraterminal gyrus is a narrow lamina on the medial surface of the hemisphere in front of the lamina terminalis, behind the parolfactory area, and below the rostrum of the corpus callosum. It is continuous around the genu of the corpus callosum with the supracallosal gyrus
- Supracallosal gyrus The supracallosal gyrus consists of a thin layer of grey matter in contact with the dorsal surface of the corpus callosum and continuous laterally with the grey matter of the cingulate gyrus
