as和什么搭配？怎么理解？

There is no doubt that pontine neurones firing in synchrony with different phases of respiration exist, and these neurones are now referred to as the pontine respiratory group (PRG).Previously known as the pneumotaxic centre, three groups of neurones were identified (inspiratory, expiratory and phase spanning) that were believed to be involved in controlling the timing of the respiratory cycle. The PRG is no longer considered to be essential for the generation of the respiratory rhythm; nevertheless, it does influence the medullary respiratory neurones via a multisynaptic pathway contributing to fine control of the respiratory rhythm as, for example, in setting the lung volume at which inspiration is terminated. There are many central afferent pathways into the PRG, including connections to the hypothalamus, the cortex and the nucleus tractus solitarius. These connections suggest that the pons coordinates the respiratory effects of numerous central nervous system (CNS) activities, including cortical control, peripheral sensory information (odour, temperature) and visceral/cardiovascular inputs.

毫无疑问，不同呼吸时相都有与之同步放电的脑桥神经元，这些神经元现在称之为脑桥呼吸组（the pontine respiratory group，PRG）。这些PRG此前被称为“呼吸调节中枢”，确定了三组神经元（吸气、呼气和跨时相），认为其参与了控制呼吸周期的切换。不再认为PRG是产生呼吸节律的必要因素，然而PRG确实通过多突触途径影响中枢呼吸神经元，协助精细控制呼吸节律，例如，设定吸气终止时的肺容积。PRG连接着许多中枢传入通路，包括与下丘脑、皮质和孤束核的中枢传入通路。这些连接表明，脑桥参与调节许多中枢神经系统（CNS）活动的呼吸效应，包括皮层控制、外周感觉信息（气味、温度）和内脏/心血管传入。
