Limbic System

Aka: Limbic System, Papez Circuit, Medial Limbic Circuit, Hippocampus, Amygdala, Septal Nuclei
  1. Definitions
    1. Limbic System
      1. Complex interconnected neural pathways in the Diencephalon and brainsterm related to emotion and motivation
      2. Integrates visceral, olfacory and somatic inputs
      3. Structures include
        1. Hippocampus
        2. Amygdala
        3. Epithalamus
        4. Gyrus cinguli
        5. Parahippocampal gyrus
        6. Hypothalamus
        7. Septal Nuclei
        8. Thalamic anterior nuclear group
    2. Septal Nuclei
      1. Grey matter in the septal region of brain inferior to corpus callosum, a part of the Telencephalon and Limbic System
      2. Septal Nuclei include dorsal, lateral, medial, triangular, septofimbrial, diagonal band, anterior commissure, stria terminalis
  2. Physiology: Medial Limbic Circuit (Papez Circuit)
    1. Function
      1. Episodic Memory appears to be a core function of the Medial Limbic Circuit (Papez Circuit)
      2. Injury to the pathway is associated with Amnesia, Alzheimer's Disease, Wernicke-Korsakoff Syndrome
    2. Pathway (in order of signals)
      1. Hippocampal formation
      2. Fornix
      3. Mammillary Bodies
      4. Mammillothalamic Tract
      5. Anterior Thalamic Nucelus
      6. Cingulum
      7. Entorhinal Cortex
      8. Hippocampal formation

Limbic System (C0023715)

Definition (NCI_NCI-GLOSS) A network of structures in the brain involved in memory and emotions.
Definition (CSP) group of brain structures associated with olfaction but of greater importance in other activities, such as autonomic functions and aspects of emotion and behavior.
Definition (MSH) A set of forebrain structures common to all mammals that is defined functionally and anatomically. It is implicated in the higher integration of visceral, olfactory, and somatic information as well as homeostatic responses including fundamental survival behaviors (feeding, mating, emotion). For most authors, it includes the AMYGDALA; EPITHALAMUS; GYRUS CINGULI; hippocampal formation (see HIPPOCAMPUS); HYPOTHALAMUS; PARAHIPPOCAMPAL GYRUS; SEPTAL NUCLEI; anterior nuclear group of thalamus, and portions of the basal ganglia. (Parent, Carpenter's Human Neuroanatomy, 9th ed, p744; NeuroNames, http://rprcsgi.rprc.washington.edu/neuronames/index.html (September 2, 1998)).

Septal Nuclei (C0036687)

Definition (FMA) Subdivision of the septum which contains the dorsal septal nucleus, the lateral septal nucleus, medial septal nucleus, triangular septal nucleus, septofimbrial nucleus, nucleus of diagonal band, nucleus of anterior commissure and nucleus of stria terminalis.
Definition (MSH) Neural nuclei situated in the septal region. They have afferent and cholinergic efferent connections with a variety of FOREBRAIN and BRAIN STEM areas including the HIPPOCAMPAL FORMATION, the LATERAL HYPOTHALAMUS, the tegmentum, and the AMYGDALA. Included are the dorsal, lateral, medial, and triangular septal nuclei, septofimbrial nucleus, nucleus of diagonal band, nucleus of anterior commissure, and the nucleus of stria terminalis.
Definition (PSY) Subcallosal nuclei that form an integral part of the limbic system. These nuclei contribute to the medial forebrain bundle and have processes synapsing in the hippocampus.
