: 我知道不可以直接求板友們幫我翻譯
: 但是我現在真的很急
: 加上我翻不太出來....
: 這是和醫學生物相關的一段英文
: 希望有強者能幫幫我
: Before anyone had recorded from bipolar cells, the big unknown was
: whether they would prove to have center-surround receptive fields,
: as ganglion cells do, and come in two types, on center and off center.
: If the answer was yes, it would almost certainly mean that the organization
: discovered by Kuffler for ganglion cells was a passive reflection of
: bipolar-cell organization.The knowledge that the receptive fields of bipolar
: cells were indeed center-surround and were of two types came from
: intracellular recordings first made by John Dowling and Frank Werblin at
: Harvard Biological Laboratories and by Akimichi Kaneko at Harvard Medical
: School. The next question is how these receptive fields are built up.
: To answer it we have to begin by examining the connections of receptors,
: bipolar cells, and horizontal cells.

在有任何人對雙極細胞進行記錄之前，最大的疑問在於這些細胞是否和神經節細胞一樣
具有中央－周邊接受區，以及是否具有「中央開啟」及「中央關閉」這兩種類型。如果
答案是肯定的，則幾乎可以確定 Kuffler 所發現的神經節組織就是種雙極細胞組織的被
動反映。雙極細胞的接受區確實是中央－周邊型且具有兩種細胞的知識，來自首次由
哈佛生物實驗室的 John Dowling 與 Frank Werblin 及哈佛醫學院的 Akimichi Kaneko
所進行的細胞內記錄。下個疑問是，這些接受區是如何建立的。為了回答這個問題，我
們必須去檢驗受器、雙極細胞，與水平細胞的連結。

※ 引述《oophs (圈圈叉叉)》之銘言：
: 原文：
: The synapses that horizontal cells make with receptors are likewise unusual,
: lacking the electron-microscopic features that would normally tell us which
: way the information is conveyed.
: It is clear that receptors feed information to horizontal cells through
: excitatory synapses because horizontal cells,
: like re-ceptors,are in most cases hyperpolarized, or turned off, by light.
: It is less clear where the horizontal cell sends its output:
: in some species such as turtles we know that they feed information back to
: receptors;in other species they make synapses with the dendrites of bipolar
: cells and doubtless feed into them;in primates we do not have either type of
: information. In summary, horizontal cells get their input from receptors;
: their output is still uncertain, but is either back to receptors, or to
: bipolar cells, or to both.

水平細胞與受器間形成的突觸也同樣不尋常：在電子顯微鏡下，它們缺乏通常可告訴
我們訊息傳遞方向的特徵。受器會透過興奮性突觸將訊息傳送給水平細胞這點是很明
確的，因為水平細胞和受器一樣，在大多情況下會被光線過極化（或關閉）。但水平
細胞在何處傳出資訊就比較不明確了。在一些如烏龜之類的物種上，我們知道水平細
胞會將訊息傳回受器；在其他物種身上，水平細胞則和雙極細胞的樹突形成突觸且無
疑會向其傳遞訊息；至於在靈長類身上，我們還沒看到其中任何一種訊息。總的來說
，水平細胞由受器接受輸入訊息；訊息的輸出方向則還不清楚，但如不是傳回受器，
就是傳給雙極細胞，或者兩者都傳。

推 chiya666:TheRock真是好人 乾脆也幫我翻一段吧 XD
推 egghead:您這玩笑開大了.
推 oophs:非常感謝T大，還有謝謝其他版友....
→ oophs:這次我是真的自己翻的...但是我知道我翻的很糟糕，所以才
→ oophs:求助於大家，真的非常謝謝
推 TheRock:以小的目前的實力，應該是沒辦法。 :p
