Highlight few important points on the ‘Limbic System’.

ANSWER 1:
[pic]

INTRODUCTION:

The limbic system is a set of brain structures including the hippocampus, amygdala, anterior thalamic nuclei, and limbic cortex that forms the inner border of the cortex. It supports a variety of functions including emotion, behavior, long term memory, and olfaction. The term "limbic" comes from Latin limbus, meaning "border" or "belt".

The Limbic system connects the higher and lower functions of our brains; it is called both the "Emotional Center" and the "Conscious System" of the brain. If we, as Humans, had to consider one part of our brains to be the core of our personal consciousness, it would be the Limbic System and, especially, the interaction between the limbic system and the cortex. Physical disruption or disease of the Limbic System causes major behavioral changes.

The human limbic system is very similar to that of primitive mammals and so it often called 'the old mammalian brain'. The hippocampus is involved in memory; someone whose hippocampus is damaged is very easily distracted and they will be unable to carry out an intended sequence of actions (e.g. making a cup of tea) because they have forgotten what they had planned to do.
The limbic system includes many structures in the cerebral cortex and sub-cortex of the brain.

The major structures are:

1. Thalami bodies
2. Hypothalamus
3. Mamillary bodies
4. Septum pellucidum
5. Cingulate gyrus
6. Hippocampus
7. Amygdala
8. Fornix
9. Olfactory bulbs

If these nine parts of the limbic system together form the chair on which consciousness sits, the focus that sits in the chair is the interaction between these nine parts and the neocortex, which is the house of our higher functions.

The cerebral hemispheres are the two largest structures at the top of the brain which enfold (and,...
