As the world goes dark, this master switch tells our pineal gland to increase levels of the hormone melatonin in the bloodstream, sort of like a chemical lullaby.

天暗下来时，这个主开关告诉我们的果体增加血液中的褪黑水平，有像化学摇篮曲。

But with nightfall comes the release of sleepy melatonin hormones from the pineal gland.

但是在晚上，就会从果体分泌褪黑。

As it gets later and dark outside, the pineal gland in your brain starts to release the hormone, and it binds to receptors deep in the brain to help usher you into dreamland.

当外面越来越晚，天黑时，你大脑中的果体开始释放荷尔蒙，它与大脑深处的受体结合，帮助引导你进入。

Every once in a while, sudden soreness triggered a twinge of discomfort and shame. Whoever said the soul and the body met in the pineal gland was a fool. It's the asshole, stupid.

每隔一阵，阵痛就会触发强烈的羞耻感。认为灵魂与肉体的交会在果体75的人，都是傻瓜。笨蛋。

As you go to sleep and finally begin to drift off, melatonin is secreted by the pineal gland which begins the sleep cycle, which happens multiple times through the night.

当你准备睡觉并开始熟睡时，果体会分泌褪黑，果体开始了睡眠周期，整个晚上会发生多次。

For example, as pinealomas, medulloblastomas, and ependymomas enlarge - the mass of the tumor can compress nearby ventricles blocking the flow of cerebrospinal fluid which causes swelling, called hydrocephalus.

例如，随着果体瘤、髓母细胞瘤与室管膜瘤的增大，巨大的肿瘤可以压迫一旁的脑室，阻断脑脊液的流动，从而引起组织肿胀，称为脑水肿。

As the sun rises, your pineal gland stops releasing melatonin.

随着太阳升起，你的果体停止分泌褪黑。

A rare supratentorial pediatric tumor is a pinealoma, which forms in the region of the pineal gland.

还有一种罕见的儿童脑幕上肿瘤：果体瘤，在果体中形成。

Histologically, prominent features include large, round tumor cells resembling germline tumors; or small cells forming Homer-Wright rosettes.

果体瘤主要的组织学特征包括类似生殖细胞肿瘤中巨大圆形的肿瘤细胞，或是形成Homer-Wright菊形团的小细胞。

Pinealomas primarily emerge from the endocrine cells of the pineal gland, and they can be grade I through IV.

果体瘤初发于果体的内分泌细胞，可分为I到IV级。

These cells are found in glands, like the supratentorial pineal gland which is located just behind the third ventricle, or the infratentorial pituitary gland located near the front of the third ventricle.

这些细胞位于腺体中，例如在第三脑室后的脑幕上果体，或是靠近第三脑室前的脑幕下垂体腺。

So, for example, a pinealoma may lead to increased secretion of the hormone beta human chorionic gonadotropin that can cause an early onset of puberty.

比如，果体瘤可能导致β人绒毛膜促性腺分泌增加，可引起青春期发育提前。

Melatonin is a hormone secreted by the pineal gland in your brain.

褪黑是由你大脑果体分泌的一种。

When the sun goes down, it is released by the pineal gland in the brain.

当太阳下山时，大脑中的果体就会释放这种物质。

Darkness allows the pineal to release melatonin.

黑暗允许果体释放褪黑。

As long as the mind is in the body, he believed, it is linked to the brain through a special brain organ which he called the pineal gland, where a constant interaction takes place between 'spirit' and 'matter.

他相信，只要思想在身体里，它就会通过一种特殊的大脑器官与大脑相连，他称之为果体，“精神”和“物质”之间不断发生相互作用。

Well, deep inside our brain we find the same structure, the pineal gland, which we also use to sense night and day, and tell us when it's time to sleep.

其实，在我们的大脑深处， 我们发现了同样的结构，果体，我们也用它来感知白天和夜晚，并告诉我们什么时候该睡觉。

And the studies indicate there may be the suggestion is there may be something somewhat different about our pineal gland, but you know, we're all good at different things.

研究表明， 我们的果体可能有些不同，但你知道， 我们每个人都有各自的特长。

Hormones are made by specialised cells mostly found in the endocrine glands, the hypothalamus, testes and ovaries, and the thyroid, parathyroid, pituitary, adrenal and pineal glands.

由特化的细胞产生，这些细胞主要存在于内分泌腺、下丘脑、睾丸和卵巢，以及甲状腺、副甲状腺、垂体、肾上腺和果体中。

Melatonin is naturally produced by your brain, and it's released by a very small gland deep within your brain called the pineal gland.

褪黑由大脑自然产生，由大脑深处一个非常小的腺体释放， 称为果体。
