Jadi di otak Teddy dan otak orang Islam yang selfish dan tidak peduli dengan kesenjangan sosial dan penderitaan orang lain itu nggak banyak "Gray Matter" nya?
Kalau bigitu kita tidak bisa menyalahkan mereka, tapi kudu disayangkan dan dikasihani aja. Tapi kita tunggu dululah konfirmasi hasil penelitian ini. http://www.sciencedaily.com/releases/2012/07/120711123005.htm Web address: http://www.sciencedaily.com/releases/2012/07/ 120711123005.htm ScienceDaily (July 11, 2012) The volume of a small brain region influences one's predisposition for altruistic behavior. Researchers from the University of Zurich show that people who behave more altruistically than others have more gray matter at the junction between the parietal and temporal lobe, thus showing for the first time that there is a connection between brain anatomy, brain activity and altruistic behavior. Why are some people very selfish and others very altruistic? Previous studies indicated that social categories like gender, income or education can hardly explain differences in altruistic behavior. Recent neuroscience studies have demonstrated that differences in brain structure might be linked to differences in personality traits and abilities. Now, for the first time, a team of researchers from the University of Zurich headed by Ernst Fehr, Director of the Department of Economics, show that there is a connection between brain anatomy and altruistic behavior. To investigate whether differences in altruistic behavior have neurobiological causes, volunteers were to divide money between themselves and an anonymous other person. The participants always had the option of sacrificing a certain portion of the money for the benefit of the other person. Such a sacrifice can be deemed altruistic because it helps someone else at one's own expense. The researchers found major differences in this respect: Some participants were almost never willing to sacrifice money to benefit others while others behaved very altruistically. More gray matter The aim of the study, however, was to find out why there are such differences. Previous studies had shown that a certain region of the brain -- the place where the parietal and temporal lobes meet -- is linked to the ability to put oneself in someone else's shoes in order to understand their thoughts and feelings. Altruism is probably closely related to this ability. Consequently, the researchers suspected that individual differences in this part of the brain might be linked to differences in altruistic behavior. And, according to Yosuke Morishima, a postdoctoral researcher at the Department of Economics at the University of Zurich, they were right: "People who behaved more altruistically also had a higher proportion of gray matter at the junction between the parietal and temporal lobes." Differences in brain activity The participants in the study also displayed marked differences in brain activity while they were deciding how to split up the money. In the case of selfish people, the small brain region behind the ear is already active when the cost of altruistic behavior is very low. In altruistic people, however, this brain region only becomes more active when the cost is very high. The brain region is thus activated especially strongly when people reach the limits of their willingness to behave altruistically. The reason, the researchers suspect, is that this is when there is the greatest need to overcome man's natural self-centeredness by activating this brain region. Ernst Fehr adds: "These are exciting results for us. However, one should not jump to the conclusion that altruistic behavior is determined by biological factors alone." The volume of gray matter is also influenced by social processes. According to Fehr, the findings therefore raise the fascinating question as to whether it is possible to promote the development of brain regions that are important for altruistic behavior through appropriate training or social norms.
