Why And How Does Laughter Come About?
The physiological study of laughter has its own name -- gelotology. And we know that certain parts of the brain are responsible for certain human functions. For example, emotional responses are the function of the brain's largest region, the frontal lobe. But researchers have learned that the production of laughter is involved with various regions of the brain. While the relationship between laughter and the brain is not fully understood, researchers are making some progress.
For example, Derks traced the pattern of brainwave activity in subjects responding to humorous material. Subjects were hooked up to an electroencephalograph (EEG) and their brain activity was measured when they laughed. In each case, the brain produced a regular electrical pattern. Within four-tenths of a second of exposure to something potentially funny, an electrical wave moved through the cerebral cortex, the largest part of the brain. If the wave took a negative charge, laughter resulted. If it maintained a positive charge, no response was given, researchers said.
During the experiment, researchers observed the following specific activities:

During the experiment, researchers observed the following specific activities:
- The left side of the cortex (the layer of cells that covers the entire surface of the forebrain) analyzed the words and structure of the joke.
- The brain's large frontal lobe, which is involved in social emotional responses, became very active.
- The right hemisphere of the cortex carried out the intellectual analysis required to "get" the joke.
- Brainwave activity then spread to the sensory processing area of the occipital lobe (the area on the back of the head that contains the cells that process visual signals).
- Stimulation of the motor sections evoked physical responses to the joke.

Laughter is triggered when we find something humorous. There are three traditional theories about what we find humorous:
The incongruity theory suggests that humor arises when logic and familiarity are replaced by things that don't normally go together. Researcher Thomas Veatch says a joke becomes funny when we expect one outcome and another happens. When a joke begins, our minds and bodies are already anticipating what's going to happen and how it's going to end. That anticipation takes the form of logical thought intertwined with emotion and is influenced by our past experiences and our thought processes. When the joke goes in an unexpected direction, our thoughts and emotions suddenly have to switch gears. We now have new emotions, backing up a different line of thought. In other words, we experience two sets of incompatible thoughts and emotions simultaneously. We experience this incongruity between the different parts of the joke as humorous.
The superiority theory comes into play when we laugh at jokes that focus on someone else's mistakes, stupidity or misfortune. We feel superior to this person, experience a certain detachment from the situation and so are able to laugh at it.
The relief theory is the basis for a device movie-makers have used effectively for a long time. In action films or thrillers where tension is high, the director uses comic relief at just the right times. He builds up the tension or suspense as much as possible and then breaks it down slightly with a side comment, enabling the viewer to relieve himself of pent-up emotion, just so the movie can build it up again! Similarly, an actual story or situation creates tension within us. As we try to cope with two sets of emotions and thoughts, we need a release and laughter is the way of cleansing our system of the built-up tension and incongruity. (According to Dr. Lisa Rosenberg, humor, especially dark humor, can help workers cope with stressful situations. "The act of producing humor, of making a joke, gives us a mental break and increases our objectivity in the face of overwhelming stress," she says
