1·Adenosine normally depresses neuron firing in many areas of the brain.

腺苷通常会抑制大脑许多区域的神经元活动。

2·During sleep, the number of sites to which adenosine is bound decreases.

在睡眠期间，腺苷结合的位点数量减少。

3·The chemical adenosine is released by brain cells when those cells are active.

这种化学腺苷是脑细胞活跃时释放的。

4·Like many other agents that affect neuron firing, adenosine must first bind to specific receptors on neuronal membranes.

像许多其他影响神经元放电的物质一样，腺苷必须首先与神经元膜上的特定受体结合。

5·Some researchers have hypothesized that it is the cumulative binding of adenosine to a large number of sites that causes the onset of sleep.

一些研究人员假设，腺苷与大量位点的累积结合导致了睡眠的开始。

6·Adenosine then binds to more and more sites on cells in certain areas of the brain, as the total amount released gradually increases during wakefulness.

当腺苷在清醒状态下释放的总量逐渐增加时，腺苷就会与大脑特定区域越来越多的细胞结合。

7·There were some apparent exceptions to the general correlation observed between adenosine-receptor binding and stimulation.

在腺苷受体结合和刺激之间的一般相关性中，有一些明显的例外。

8·ATP stands for adenosine triphosphate.

at p代表三磷酸腺苷。

9·It blocks adenosine, a chemical that makes you drowsy.

它阻挡腺苷，腺苷是一种使你昏昏欲睡的化学物质。

10·It blocks the connection of adenosine to nerve cells.

它阻碍腺苷与神经细胞之间的联系。
