2、 higher risk of suffering from mood disorders.But exactly how the inner workings of the urban and rural minds cause this difference has remained unclearuntil now.A study just published in Nature by Andreas Meyer Lindenberg of the University of Heidelberg and his colleagues has used a scanning techni

3、que called functional magnetic resonance imaging(功能性磁共振成像，简称fMRI)to examine the brains of city dwellers and countrymen when they are under stress.In Dr Meyer Lindenbergs first experiment，participants lying with their heads in a scanner took maths tests that they were bound to fail(the researchers ha

5、of the rural countrymen.However，their brains dealt with the stress caused by the experimenters in different ways.These differences were noticeable in two regions：the amygdalas(杏仁核)and the perigenual anterior cingulate cortex(前扣带皮层，简称PACC)People living in the countryside had the lowest levels of acti

6、vity in their amygdalas.Those living in towns had higher levels.City dwellers had the highest.In the case of the PACC，however，what mattered was not where someone was living now，but where he or she was brought up.The more urban a persons childhood，the more active his PACC，regardless of where he was d

7、welling at the time of the experiment.The amygdalas thus seem to respond to the hereandnow while the PACC is programmed early on，and does not react in the same，flexible way as the amygdalas.Secondtosecond changes in its activity might，though，be expected to be connected with changes in the amygdalas，

8、because of its role in regulating them.fMRI allows such connections to be measured.In the cases of those brought up in the countryside，regardless of where they now live，the connections were as expected.For those brought up in cities，however，these connections broke down.The regulatory mechanism of th
