• 
  
  The hippocampus is an area of the brain
  海马是大脑中
• 
  
  that's very involved in memory and in concentration.
  与记忆和注意力集中相关的区域
• 
  
  And in people with chronic depression,
  有慢性抑郁症的人
• 
  
  you often see shrinkage in the hippocampus,
  通常海马萎缩
• 
  
  and this may be related to their problems in concentration and attention.
  这就造成了他们注意力不能集中的问题
• 
  
  And then finally, the anterior cingulate is an area of the brain
  最后 大脑中前扣带皮层
• 
  
  that's involved in a lot of different activities,
  是与很多行为有关的区域
• 
  
  but pertinent to the mood disorders,
  也与情感障碍有关
• 
  
  particularly in responses to distress--to stress
  尤其是对悲痛和压力的反应
• 
  
  and in sort of the choice of behaviors.
  以及一些选择行为
• 
  
  And it may be that dysregulation of the anterior cingulate may be involved
  可能前扣带皮层的失调
• 
  
  in the person's difficulty in responding appropriately to stress,
  会造成患者应对压力的困难
