Laughter is an emotional expression. Most common causes for laughter are sensations of joy or humor. However in some situations it can be interpreted as a symptom.Scientifically is proved that laughter is controlled directly by brain. Although there are no known laughter centers in the brain it is known that parts of the limbic system are involved in the process of laughter. Two structures in the limbic system are involved in producing laughter: the amygdale and the hippocampus but still it is not completely cleared.
A study shows that stress-related hormones decreased during episodes of laughter, which provides support for the claim that humor can relieve stress. In other words, funny stories can relieve stress and it is scientifically proved.
Abnormal laughter as an expression is almost the same as normal. The only and the biggest difference is the cause. The causes of an abnormal laughter are diseases. In most cases the diseases are pseudo bulbar palsy and gelastic epilepsy. Laughter acts like a symptom here. In fact, huge amounts of abnormal laughter may cause a person to lose consciousness.
Laughter is a signal that either we send to others in order to get a reaction, express emotions. Otherwise it can be a signal that there is something wrong with our bodies and we need help.
