Mouse love to laugh you know: there are ticklish neurons in the brain (Figure) happy mouse love smile: this phenomenon is confirmed by scientists, mice laugh really is a kind of enjoyment, and they will only be in a good mood circumstances will laugh. The researchers found that when the mice were scratching teasing, emits an ultrasonic laughter". The scientists found that by scratching teasing way, can make the mouse laugh. However, the frequency of their laughter is high, people generally do not hear. Sina Technology News Beijing on November 14th news, according to foreign media reports, a mention of mice, people will always be associated with the plague and other bad things, will feel evil and fear. In fact, the mouse also has its lovely side, the mouse loves to laugh. Scientists have found that mice love to laugh, is really a kind of enjoyment, and they will only be in a good mood to laugh. Researchers at the Humboldt University Berlin in Germany in the brains of mice found a ticklish and laugh related neurons by stimulation of the neurons, causing the mouse giggling. The results of the study are published in the Journal science. This finding suggests that the somatosensory cortex in the region of the brain may play a role in mood changes. It was generally believed that this area of the brain is primarily associated with touch. Related in a previous study, scientists have found that by scratching teasing way, can make the mouse laugh. However, the frequency of their laughter is high, people generally do not hear. Although scientists know very easily through scratching teasing mice laugh, but they still can not understand the principle, that is how to get this feeling in the mouse brain. In order to solve this problem, researchers Shimpei Ishiyama and the activity of neurons in Michael Brecht of rat brain in the somatosensory cortex were monitored, and the changes of neuronal activity before and after scratching were analyzed. In previous studies of mouse scratching is feedback, the rats seemed ready to wait for the scratching hand, and show a "Happy Dance", and "giggle" sound sound wave. After a comparative analysis, the researchers found that their results were consistent with previous studies. In order to verify this correlation, researchers in mice has not been scratching on the somatosensory cortex neurons of the stimulus at this time, they found that the mice were scratching will also be laughing because of neuronal stimulation. However, when the mouse is anxiety, for example, it is placed in a very high platform, the scratching and neuronal stimulation effect is not good, the mouse suppressed laughter. Scientists believe that their findings may prove a viewpoint of Darwin, "if scratching caused laugh, then (laughter) mood is certainly in a pleasant state." (bin)相关的主题文章:
