The study of emotion was once relegated to the backwaters of neuroscience, a testament to the popular conception that what we feel exists knocked out(p)side our mentalitys, acting b arly to intrude on commonplace thought. The science has changed Emotion is now considered intact to our over-all mental health. In mapping our emotions, scientists arouse found that our emotional school principal overlays our thinking header The two exist forever intertwined.      There is a critical interplay between reason and emotion. We are well aware of how brain malfunctions can cause pain, depression, and emotional paralysis. We must also understand that the brain affects positive emotional responses such as laughter, excitement, happiness, and love. Scientists have been able to locate the section of the brain that causes laughter.     Some clues for the physiological basis of laughter have come from people who suffered brain injuries, strokes or neu rological diseases. C.B., a landscaper in Iowa, is one of them. Three years ago, at the age of 48, C.B. suffered a stroke. Fortunately, he recovered quite well and was expected to return to his normal life. However, since the stroke, C.B. and those around him, have been perplexed by certain changes in his behavior. though he seems healthy, and doesnt suffer any pain, occasionally, for no noticeable reason, he bursts out into uncontrollable, wild laughter. In other cases, out of the blue, he is swept into weeping in a similar attack.     C.B. has joined a long tip of clinical cases that are described in medical literature as pathological laughter and crying (PLC). All of these patients suffer from brain vituperate that has destroyed or impaired small areas in their brains. Usually, the lesions are no bigger than a few cubic millimeters. However, since the lesions do not eer occur exactly in the same spot in the brain, it is concentrated to determine based on these cases, which brain areas are in press of laughter. Nevertheless, PLC suggests an interesting linkage the same tiny lesion can cause twain laughter and crying. That means that the same brain regions are involved in both laughter and crying. But most surprisingly, these laughter and crying are not associated with mirth or sadness. PLC patients suffer from "mechanical laughter". The lovely feelings, happiness, amusement or joy that usually accompanies laughter are absent. Patients equal C.B. often even suffer anxiety and fear with their laughter.      The case of a French woman who suffered from Parkinsons disease sheds more light on the association between laughter, crying and emotions.
