n. 腺苷
网络 腺苷; 腺甘酸; 腺嘌呤核苷
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。
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。
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。
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。
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。
