Where does our emotion exist?

What I always think about people's psychology very mysterious is that when we're watching some drama we can't help having our emotion captured to the drama that sometimes let us build some illusion as if the drama is real story.(It must be similar to that of "it's me faud" occasion.)

I know one scholar who try to simulate such human psychology by advanced computer.

While other brain science like cyborg technology only enables to extract only simple instruction from the brain for handicapped people,what's occurring in the brain while watching drama must be much complicated and harder to interpret by computer.This problem is associated with religious riddle where our emotion exists.
