smiles versus brain

There are two types of smiles:
  • the first type is when human are in a situation where they think " i want to smile..." the brain's frontal cortex, which deals with emotion takes delicate control of the facial muscles to create a natural smile.
  • conversely, if you try to force yourself to smile the locomotor center sends the order "SMILE" to control the muscles. but, that doesn't go very well. the smile always ends up looking awkward.
in order to smile naturally, the frontal lobe which controls emotion creates it :)
