神经心理学研究大脑的解剖结构如何影响某人的行为,情绪和认知。多年来,大脑科学家已经表明大脑的不同部分负责特定的功能,无论是识别颜色还是解决问题。与百分之十的神话相反,科学家们已经证明,由于正电子发射断层扫描和功能磁共振成像等大脑成像技术,大脑的每个部分都是我们日常功能不可缺少的部分。研究尚未发现一个完全无效的大脑区域即使是在单个神经元水平测量活动的研究也没有发现任何非活动区域的大脑。当一个人做特定任务时,许多测量大脑活动的脑成像研究显示了大脑不同部分如何协同工作。例如,当您在智能手机上阅读这些文本时,大脑的某些部分,包括负责视觉的部分,阅读理解和握住你的手机将更加活跃。然而,一些大脑图像无意中支持了百分之十的神话,因为它们通常在另外一个灰色的大脑上显示出明亮的斑点。这可能意味着只有亮点才具有大脑活动,但事实并非如此。有色斑点代表大脑区域,当某人做某项任务时,相比之下,这些斑点更加活跃,灰色斑点仍然存在积极但较轻的程度。与百分之十的神话更直接的对立在于遭受脑损伤的人 – 例如通过中风,头部创伤或一氧化碳中毒 – 以及他们不能再做什么或做什么同样,由于这种损害。如果百分之十的神话是真的,那么对我们的大脑的许多部分的损害不应该影响你的日常运作。研究表明,破坏大脑的一小部分可能会造成毁灭性的后果。例如,如果某人遭受了布罗卡地区的损害,他们可以理解语言,但无法正确地形成文字或流利地说话。在一个高度宣传的案例中,佛罗里达州的一名女性永远失去了她“思想,感知,记忆和情感的能力那是人类的本质“,当缺氧破坏了她大脑的一半 – 占大脑的85%。

Neuropsychology studies how the anatomy of the brain affects someone’s behavior, emotion, and cognition.Over the years, brain scientists have shown that different parts of the brain are responsible for specific functions, whether it’s recognizing colors or problem solving. Contrary to the ten-percent myth, scientists have proven that every part of the brain is integral for our daily functioning thanks to brain imaging techniques like positron emission tomography and functional magnetic resonance imaging.Research has yet to find a brain area that is completely inactive. Even studies that measure activity at the level of single neurons have not revealed any inactive areas of the brain. Many brain imaging studies that measure brain activity when a person is doing a specific task show how different parts of the brain work together.For example, while you are reading this text on your smartphone, some parts of your brain, including those responsible for vision, reading comprehension, and holding your phone, will be more active.Some brain images, however, unintentionally lend support to the ten-percent myth because they often show small bright splotches on an otherwise gray brain. This may imply that only the bright spots have brain activity, but that isn’t the case.Rather, the colored splotches represent brain areas that are more active when someone’s doing a task compared to when they’re not, with the gray spots still being active but to a lesser degree.A more direct counter to the ten-percent myth lies in individuals who have suffered brain damage – like through a stroke, head trauma, or carbon monoxide poisoning – and what they can no longer do, or do as well, as a result of that damage. If the ten percent myth is true, then damage to many parts of our brain shouldn’t affect your daily functioning.Studies have shown that damaging a very small part of the brain may have devastating consequences. If someone experiences damage to Broca’s area, for example, they can understand language but can’t properly form words or speak fluently.In one highly publicized case, a woman in Florida permanently lost her “capacity for thoughts, perceptions, memories, and emotions that are the very essence of being human” when a lack of oxygen destroyed half of her cerebrum – which makes up about 85 percent of the brain.
