Mosquitoes are very sensitive to heat and light (indeed, their sensitivity to infra-red radiation helps them sense the presence of food, in the form of people).
蚊子对光和热非常敏感（事实上，它们对红外辐射的敏感帮助它们感应其食物——人的存在）。

Results: the sensitivity to high and low dose ionizing radiation was distinct in different area of the cortex.
结果：淋巴结皮质的不同区域对高、低剂量电离辐射的敏感性均不同。
