Study Notes
Limbic System Definition
- Also known as visceral brain, old brain, or rhinencephalon
- Consists of limbic lobe proper and additional structures
Limbic Lobe Proper
- Comprised of cerebral components:
- Subcallosal gyrus
- Cingulate gyrus
- Isthmus
- Parahippocampal gyrus
- Includes hippocampal formation:
- Subiculum
- Hippocampus (Ammon's horn)
- Dentate gyrus
- Also includes amygdala (archistriatum)
Limbic System Concept
- Includes additional structures:
- Hypothalamus
- Thalamus (dorsomedial)
- Habenula
- Brainstem
- Prefrontal cortex
Main Divisions of Limbic Lobe
- Hippocampal formation:
- Hippocampus: 3 layers, output
- Dentate gyrus: 3 layers, input molecular
- 1 pyramidal (5) or granules (4)
- Subiculum: >3layers
