We discovered that the lateral bed nucleus stria terminalis (BST) is involved in the pain response during formalin test. Conversely, the function of the lateral BST influences the pain response by the formalin. This concept indicates the emotion and pain is related to each other. CRH neurons are expressed the brain area such as the periventricular hypothalamus associated with stress and the central amygdala related to outflow of the emotional response. Thus, CRH neurons in the lateral BST may be involved in emotion side during the formalin test. To this end we must label CRH neurons as fluorescence since we will analyze by patch-clamp technique. So we are now generating transgenic mouse which CRH neurons have bright fluorescence and useful for electrical analyse.

我们发现，在福尔马林测试期间，侧床核末端（BST）参与了疼痛反应。相反，侧BST的功能会影响福尔马林的疼痛反应。这个概念表明情绪和痛苦彼此相关。 CRH神经元表达了大脑区域，例如与压力相关的脑室下丘脑和与情绪反应流出相关的中央杏仁核。因此，在福尔马林测试期间，BST侧BST中的CRH神经元可能参与情感方面。为此，我们必须将CRH神经元标记为荧光，因为我们将通过贴片钳技术进行分析。因此，我们现在正在生成CRH神经元具有明亮荧光的转基因小鼠，可用于电分析。
