retrograde degeneration

Methods After retrograde degeneration of the facial motoneurons induced by section of the facial nerve, the discharge of non-motoneurons in the facial nucleus was extracellularly monitored, and their phase relations to the respiratory cycle were investigated.

方法在切断面神经引起面运动神经元逆行溃变后，细胞外记录面神经核内非运动神经元的单位放电，观察其放电样式与呼吸周期的关系。

The study also indicated that the ischemia of the peripheral nerve led to retrograde degeneration.

研究表明.周围神经局部缺血亦可导致逆行性胞体变性。
