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.

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，你大脑中的松果体开始释放荷尔，大脑深处的受体结合，帮助引导你进入梦乡。

And the master gland in your body is the pituitary, which produces many hormones that signal other glands — like the thyroid, parathyroid, adrenal, and pineal glands — to make their own hormones.

你体的主要腺体是垂体，产生许多荷尔，向其他腺体发出信号——比腺、旁腺、肾上腺和松果腺——制造自己的荷尔。

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。认为灵魂肉体的交会点在松果体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，松果体会分泌褪黑激素，松果体开始了睡眠周期，整个晚上会发生多次。

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

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

松果体瘤初发于松果体的分泌细胞，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，例在第三脑室后的脑幕上松果体，或是靠近第三脑室前的脑幕下垂体腺。

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

褪黑素是由你大脑松果体分泌的一种激素。

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

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，就会通过一种特殊的大脑器官大脑相连，他称之为松果体，“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，松果体，我们也用来感知白天和夜晚，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， 我们的松果体可能有些不同，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.

激素由特化的细胞产生，这些细胞主要存在于分泌腺、下丘脑、睾丸和卵巢，以及腺、副腺、垂体、肾上腺和松果体中。

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

褪黑激素由大脑自然产生，由大脑深处一个非常小的腺体释放， 称为松果体。

All they way up here at the top of our head, like with the pineal gland, the pituitary gland.

一直往上到我们头的顶部，比松果体和垂体。
