Weak stimulation, delivered for 10 minutes and repeated four times at 30-minute intervals, worsened overeating and the desire for fatty foods, causing the mice to consume nearly three quarters of their daily food intake, and to gain weight.

　　句子的解析：

　　词汇突破：

　　1.Activate 激活

　　2.Neuron 神经元

　　3.Immediately 立即

　　4.Binge eating 暴食

　　5.Preference 偏好

　　6.Stimulation 刺激

　　7.Worsen 恶化

　　8.Overeating 过量饮食

　　第一句：

　　They found activating these neurons immediately caused binge eating, making the mice eat more than one third of their daily food rations in just 10 minutes, and increasing their preference for high-fat foods.

　　确定主干：

　　They found (that)

　　他们发现

　　切分成分+独立成句：

　　1.(Activating these neurons动名词做从句主语) immediately caused binge eating

　　激活这些神经元会立即导致暴食行为

　　2. making the mice eat more than one third of their daily food rations in just 10 minutes

　　=Activating these neurons makes the mice eat more than one third of their daily food rations in just 10 minutes

　　(令老鼠在短短10分钟内吃掉超过日常食物配给的三分之一)

　　3. increasing their preference for high-fat foods.

　　= Activating these neurons increases their preference for high-fat foods.

　　(并提升了它们对高脂食物的偏好)

　　参考译文：他们发现激活这些神经元会立即导致暴食行为，令老鼠在短短10分钟内吃掉超过日食物配给的三分之一，并提升了它们对高脂食物的偏好。

　　第二句：

　　Weak stimulation, delivered for 10 minutes and repeated four times at 30-minute intervals, worsened overeating and the desire for fatty foods, causing the mice to consume nearly three quarters of their daily food intake, and to gain weight.

　　确定主干：

　　Weak stimulation worsened overeating and the desire for fatty foods

　　切分成分+独立成句:

　　1.causing the mice to consume nearly three quarters of their daily food intake, and to gain weight.

　　=Weak stimulation causes the mice to consume nearly three quarters of their daily food intake, and to gain weight

　　2. delivered for 10 minutes and repeated four times at 30-minute intervals定语

　　每隔30分钟释放长达10分钟的并重复四次的

　　参考译文：而每隔30分钟释放长达10分钟的弱刺激并重复4次会令过量饮食和对对高脂食物的欲望更糟，让老鼠吃掉几乎日常食物配给的四分之三，并增加体重。

　　背景介绍：

　　深部脑刺激治疗通过在病人的大脑的特定区域放置电极(electrodes)，并传输高频电脉冲来干预目标脑组织的神经元活动。迄今为止，全球有约10万名帕金森病人接受过这种治疗，他们诸如震颤和僵硬等症状因之得到有效控制。耶鲁医学院的神经外科医生们受到启发，尝试通过刺激实验小白鼠的不同大脑区域，以求确定与过度饮食相关的神经元通路。他们在丘脑底核(subthalamic nucleus)的未定带(zona incerta)细胞组织中注入经过遗传处理的病毒(genetically engineered virus)，该病毒会将一个基因传输(carried a gene into)给这些细胞，令细胞表达一系列光敏通道蛋白(channelrhodopsin)。这些细胞会因此对光照敏感(sensitive to light)，使研究者得以利用光导纤维传送激光脉冲，达到高精度激活(activate with great precision)的效果。
