指水生动物体表侧线器的末梢器官。在体表分散存在者称为游离神经丘,其呈孔状者称为孔器,在皮下以一或数条管状而存在者称为管器(canal org-an)
体侧线的组成有两种,一是劳伦氏壶腹(AmpullaeofLorenzini),二是神经丘(Neuromasts)。后者是众多的感受细胞,它们的感觉.

当图象消失了,因为不确定该往哪看,上视丘神经活动会出现起伏现象,引起微眼跳。
When images begin to fade, the uncertainty about where to look increases the fluctuations in superior colliculus activity, triggering a microsaccade.
嗜睡症似乎是由基因遗传导致的,该遗传会是人体无法吸收或产生足够的神经下视丘分泌素。
Narcolepsy is apparently caused by a genetic glitch that prevents the body from either absorbing or producing enough of the neurochemical hypocretin.
饥饿这种感觉虽然很复杂,却也是由视丘下部的神经元所决定的,它将信号传给大脑,告知大脑你是饥饿抑或过撑。
Hunger is a complex sensation, but it is determined in part by neurons located in the hypothalamus, which send signals to the brain telling it that you're either hungry or sated.
