|
Which areas did Broca include in his understanding of the limbic system? (4) |
1. Cingulate gyrus 2. Subcallosal gyrus 3. Parahippocampal gyrus 4. Hippocampal formation |
|
|
What was Papez's contribution to the understanding of the Limbic system? (3) |
1. He drew a precise circuit 2. Contributed to Broca's understanding 3. Showed the link to emotional processing |
|
|
Explain the structure of the limbic system with reference of the its constituent brain regions (9) |
1. Includes all structures in the medial and basal parts of the cerebral hemispheres 2. Cingulate gyrus superior 3. Shaped around the corpus callosum 4. Amygdala 5. Forinx 6. Septum 7. Olfactory bulb 8. Mammilary bodies 9. Anterior nucleus of the Thalamus |
|
|
What are the 3 sources of input to the limbic system? (4) |
1. Posterior association cortex 2. Inferotemporal cortex via entorhinal cortex 3. Frontal cortex |
|
|
What 2 structures of the limbic system project to the frontal cortex and why? (3) |
Hypothalamus & amygdala. This projection is to allow one to make a decision with the given limbic information |
|
|
Elaborate on the function of the limbic system (5) |
- no structure-function system in the limbic system - great deal of interconnectivity - Primary functions include: 1. Hippocampus proper - memory acquisition 2. Amygdala - emotional processing (eg. fear processing) 3. Hypothalamus - regulation of emotional behaviour (incl. rage) |
|
|
What pathology can arise from the limbic system? Elaborate where necessary (3) |
1. Behavioural problems 2. Wernicke-Korsakoffs syndrome - degeneration of the mammillary bodies |
