morphological concept of the limbic lobe? Includes what types of cortex?
|
oldest telencephalic structures; forms border around diencephalon
Proisocortex, Periallocortex, Allocortical structures, Subcortical structures |
|
|
Subcortical structures of limbic lobe?
|
• Basal Forebrain (Septal nuclei, Diagonal band, Nuc basalis)
• Amygdala (archistriatum) |
|
|
Allocortical structures of limbic lobe?
|
• Hippocampus (archicortex)
• Prepyriform / Primary Olfactory Cortex (paleocortex) |
|
|
Periallocortex of limbic lobe?
|
• Entorhinal Cortex & Presubiculum
|
|
|
Proisocortex of limbic lobe?
|
• Cingulate Cortex
• Orbitofrontal Cortex • Posterior Parahippocampal Cortex |
|
|
what is the lymbic SYSTEM?
|
Limbic lobe PLUS closely associated (ie. directly connected) parts of diencephalon & mesencephalon
|
|
|
What is added to the limbic lobe to make the limbic system?
|
-hypothalamus
-thalamus -Mesencephalon = “Limbic Midbrain Area” (LMA); VTA; Central gray -Epithalamus = Habenula |
|
|
Describe the difference between allocortex of the limbic system and the neocortex of the forebrain
|
o Neocortex → 6 layers, heavy 2/3 where cortico-cortico connections are
o Allocortical structures → 3 layered cortex |
|
|
olfactory bulb projections?
|
-primary olf cortex
-amygdala -entorhinal cortex -> hippocampus |
|
|
Describe how the connections of the basal forebrain may account for the role of acetylcholine in
cortical information processing |
-Basal forebrain consists of 3 main cholinergic nuclei = Septal nuclei, Diagonal band nuclei, and Nucleus basalis.
-These neurons project to multimodal association areas, amygdala, fornix>hippocamus, hypothalamus, cingulate |
