The Power of Emotional Speeches

The brains of the different people listening to those speeches started synchronizing. This is not only in regions that are important for language and hearing, it's also in regions which are important for emotion. If a story teller or the person giving the speech is able to elicit emotion in the other person then heis actually having somewhat of a control on that person's state of mind. So by eliciting emotion, what you are able to do is change the perception of everything that comes after.
