Anyone has any idea how does the brain regulate/suppress/modify emotions?
I don't need just the name of the brain region but also actual way it interacts with and overrides emotions.

For example it was dark and i was afraid and i convinced myself to not be afraid.
It is supposed to be instinctual to be afraid of the dark for the obvious evolutionary reasons but i "conquered" my emotions by reasoning.

How is that possible?
