2016年雅思閱讀長難句翻譯：神經(jīng)沖動(dòng)

Although qualitative variance among nerve energies was never rigidly disproved，the doctrine was generally abandoned in favor of the opposing view，namely，that nerve impulses are essentially homogeneous in quality and are transmitted as "common currency" throughout the nervous system.
    盡管在神經(jīng)能量上存在著質(zhì)的不同，這一點(diǎn)從來都沒有在嚴(yán)格的意義上被反對(duì)過，但是以上教條通常被拋棄掉，而轉(zhuǎn)向相反的觀點(diǎn)，即：神經(jīng)沖動(dòng)從根本上本質(zhì)相同，而且被當(dāng)作"一種普通流"在整個(gè)神經(jīng)系統(tǒng)中傳播。
