I'm about to remove the locus coeruleus, which is incredibly delicate work. Have at it.

我正要切除蓝斑，这活儿需要相当的技巧。你来吧。

It's not. I'll have you know, in the field of physics, we work with particles so small, they make fat jokes about the locus coeruleus.

确实，给你说啊，在物理领域，我们研究的粒子都超小，见到蓝斑都得笑它胖。

Pupil size is related to activity in the locus coeruleus, a nucleus situated in the upper brain stem with far-reaching neural connections to the rest of the brain.

瞳孔大小与蓝斑的活动有关，蓝斑是位于上脑干的一个核， 与大脑的其他部分有着深远的神经联系。

One hypothesis is that people who have larger pupils at rest have greater regulation of activity by the locus coeruleus, which benefits cognitive performance and resting-state brain function.

一种假设是， 在静止状态下瞳孔较大的人对蓝斑的活动有更大的调节作用，这有利于认知表现和静息状态下的大脑功能。

The locus coeruleus releases norepinephrine, which functions as both a neurotransmitter and hormone in the brain and body, and it regulates processes such as perception, attention, learning and memory.

蓝斑释放去甲肾上腺素，它在大脑和身体中既是神经递质又是激素，它调节感知、注意力、学习和记忆等过程。
