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