ScienceDaily (May 19, 2010) — New research shows a possible explanation for the link between mental health and creativity. By studying receptors in the brain, researchers at Karolinska Institutet have managed to show that the dopamine system in healthy, highly creative people is similar in some respects to that seen in people with schizophrenia. 卡洛琳斯卡学院发现，通过量测多巴胺的受器，高创造力的正常人和精神分裂病患有相 似的表现。 High creative skills have been shown to be somewhat more common in people who have mental illness in the family. Creativity is also linked to a slightly higher risk of schizophrenia and bipolar disorder. Certain psychological traits, such as the ability to make unusual pr bizarre associations are also shared by schizophrenics and healthy, highly creative people. And now the correlation between creativity and mental health has scientific backing. 以前就知道一些精神疾病患者有着高的创造力，而高创造力也和患精神分裂的风险相关。 现在这些关联有了背後的依据。 "We have studied the brain and the dopamine D2 receptors, and have shown that the dopamine system of healthy, highly creative people is similar to that found in people with schizophrenia," says associate professor Fredrik Ullén from Karolinska Institutet's Department of Women's and Children's Health, co-author of the study that appears in the journal PLoS ONE. 这篇论文发表在Plos ONE，研究多巴胺的D2受器，得到上述的结果。 Just which brain mechanisms are responsible for this correlation is still something of a mystery, but Dr Ullén conjectures that the function of systems in the brain that use dopamine is significant; for example, studies have shown that dopamine receptor genes are linked to ability for divergent thought. Dr Ullén's study measured the creativity of healthy individuals using divergent psychological tests, in which the task was to find many different solutions to a problem. 在这篇论文以前，这关系还保有着神秘而不为人知，现在发现多巴胺的重要角色。之前 多巴胺就被认为与发散性思考有关。Dr Ullén利用发散性的心理测验来量测创造力。 （找出对於一个问题有多少种解决方法。） "The study shows that highly creative people who did well on the divergent tests had a lower density of D2 receptors in the thalamus than less creative people," says Dr Ullén. "Schizophrenics are also known to have low D2 density in this part of the brain, suggesting a cause of the link between mental illness and creativity." 高创造力者在发散性测试中都表现良好，在视丘也有密度较低的D2多巴胺受器。也因此怀 疑精神疾病与创造立的关系。 The thalamus serves as a kind of relay centre, filtering information before it reaches areas of the cortex, which is responsible, amongst other things, for cognition and reasoning. 视丘像是中继站，过滤从皮质来的资讯，负责各方面的认知活动。 "Fewer D2 receptors in the thalamus probably means a lower degree of signal filtering, and thus a higher flow of information from the thalamus," says Dr Ullén, and explains that this could a possible mechanism behind the ability of healthy highly creative people to see numerous uncommon connections in a problem-solving situation and the bizarre associations found in the mentally ill. 在视丘的比较少的D2受器，可能表示低程度的资讯过滤，因此可以传递较多的讯息。 Dr Ullén认为这是为什麽高创造力的人可以有那麽多鬼点子也而与精神疾病有关。 "Thinking outside the box might be facilitated by having a somewhat less intact box," says Dr Ullén about his new findings. -- 有点乱翻，有错请指正，顺便最後一句不太懂如何翻 xD 不过这研究真的蛮有趣的，只是不知道怎麽用於治疗精神分裂或增加创造力。 弄不好变成没创造力又精神分裂就糟了 0rz 原网址： http://www.sciencedaily.com/releases/2010/05/100518064610.htm --
