Ultrastructural changes were followed in the isolated mechanoreceptor neurons of the crayfish during post-excitational short-term trace processes (i.e. acceleration of the adaptional state), after repeated adaquate excitations. Fibrillar rearrangements of the mitochondrial cristae in the axonal mitochondria took place at the moderate excitation, no visible changes being seen in the somatic mitochondria and other organelles. However, the swelling of periaxonal areas and the rupture between strands of microtubules and electrogenic membrane occurred at the end of the fatique stimulation. In addition, the swelling of somatic mitochondria in the perinuclear zone and of the reticulum was noticed. Besides, the survival time of the excited isolated neurons strongly depended on the functional state of the surrounding glial cells. It is suggested that energetic processes are strongly involved in the postexcitational short-term traces.
在重复给予适宜刺激后，对小龙虾离体机械感受器神经元在兴奋后短期痕迹过程（即适应状态加速）中进行超微结构变化追踪。适度兴奋时轴突线粒体的线粒体嵴发生纤维状重排，胞体线粒体和其他细胞器未见明显变化。然而，疲劳刺激结束时轴周区域肿胀，微管和电生膜之间的条索断裂。此外，还观察到核周区域胞体线粒体和内质网肿胀。此外，兴奋的离体神经元的存活时间强烈依赖于周围神经胶质细胞的功能状态。提示能量过程在兴奋后短期痕迹中起重要作用。
