In Dr Meyer-Lindenbergs first experiment, participants lying with their heads in a scanner tookmaths tests that they were doomed to fail . To make the experience still more humiliating, the team provided negativefeedback through headphones, all the while checking participants for indications of stress, suchas high blood pressure.
在迈耶-林登贝格博士的第一个实验中,参与者躺着头枕在一个扫描器上接受他们注定要失败的数学测验。为了使这活动更加具有羞辱性,研究人员通过耳机给予参与者消极的回答,并一直检测参与者表现出的压力反应,如高血压。
The urbanites general mental health did not differfrom that of their provincial counterparts. However,their brains dealt with the stress imposed by theexperimenters in different ways. These differenceswere noticeable in two regions: the amygdalas andthe perigenual anterior cingulate cortex . Theamygdalas are a pair of structures, one in eachcerebral hemisphere, that are found deep inside thebrain and are responsible for assessing threats andgenerating the emotion of fear. The pACC is part ofthe cerebral cortex that regulates the amygdalas.
都市人总体的心理健康状况与他们所在地区的其他人没有什么差别。但是,他们应对实验者给予压力的方法不同。这些差别主要在两地地方:杏仁核和扣带皮层部分。杏仁核有一对,大脑左右半球各一个,它在大脑深处,与判断威胁和产生害怕情绪有关。扣带皮层部位是大脑皮层的一部分,它对杏仁核进行调节。
