What are emotions, and why do we have them? | HowStuffWorks
Emotions are a basic response to change, both internal and external, sometimes simultaneously. While our mood lasts for hours or even days, emotions are fleeting, like waves.
Emotions are a spontaneous, motivating agent of change, making us act in our most natural, human way, before the mind comes in the picture, which looks at other signals before reacting.

The placebo effect happens when a person takes medication that he thinks will help, but the medication has not been proven to be effective for the specific condition.

However, studies show that a placebo doesn't trick the brain - the brain reacts differently to a drug than a placebo. A 2004 study showed that the expectation of pain relief causes the brain's relief system to activate.
Placebos are often used in clinical drug trials to determine how well a potential medicine will work.

Scientists do not fully understand misophonia but suspect it's caused by the way some people's brains process particular sounds and react to them.
Some studies found that the brains of people with misophonia showed hyperactivation of the salience network, a group of brain areas that direct our attention to important things in our surroundings. Trigger sounds send the salience network into an overdrive. Researchers found these brain areas are structurally more robust in people with misophonia.
There's a lot of similarity between people who experience misophonia, but also a lot of diversity.
Therapists use a variety of techniques that is often based on the symptoms. Those who experience fear and anxiety may respond to exposure-based treatments. Those who experience anger can learn to manage their distress through distraction or relaxation techniques.
