1·Extroverts have more brain activity in the posterior thalamus and posterior insula. These parts of the brain are associated with sensory input.
外向人的后侧丘脑，后侧岛叶比较活跃，而大脑的这两个部分是和知觉输入有关联的。
2·Spindles, which only appear when we are asleep, are generated by a brain region called the thalamus.
产生纺锤波的大脑区域叫做丘脑，它只会在我们睡着了的时候出现。
3·From the thalamus, the "itch" message is passed to the cerebral cortex, which interprets the signals and produces the sensation of itch.
“痒”的信息从丘脑传递到大脑皮层，由大脑皮层解释这个信号，并产生痒的感觉。
4·In other words, the brain is active even when we are asleep - and the more active the thalamus, the better we sleep.
换句话说就是，当睡着了的时候，我们的大脑仍然是活动的，并且丘脑的活动越频繁，我们就睡的越好。
5·While most sensory information is “processed” by the thalamus before being sent on its way, Ellenbogen says, light goes directly to the circadian system.
大多数感觉信号都经过丘脑处理才会发动到特定中枢，而光线刺激直接影响生物钟系统。
