Answer 6

I know why that part exists, though not it's name.

To be accepted by the pack, one must appear human.

The saddest thing in this context is that often, those who do not express their emotions are feeling pain and suffering on an entirely different level from those who do.

It is good, if you can express your emotions - it shows that you can repair the damage done, and gives others confidence in you.

When people look upon the solemnity of those who quietly suffer, they feel fear.

Fear for the person suffering, because they are unable to articulate their emotions, Fear for the people around them, because that suffering could turn into hatred, and Fear for themselves, because they are unable to comfort the one who suffers in silence.

edit: It hurts that there are those who are unable to share their thoughts through writing a response, and hide behind the ratings.

Answer 7

Emotion is not confined to a single brain region...in fact many have argued (for over a century) that emotion is not even confined to the brain! See my previous answer on emotion for more information:

Answer 8

I think it's the frontal lobe.  

Answer 9

Hypothalamus assembles certain chemicals that matches certain emotion that we experience. Those particular chemicals are called peptides. They are small-chain amino acid sequences.

So the release of a particular peptide will result in expressing a particular emotion.
