The effects of adequate stimuli upon the ganglion cells of the ganglion vestibulare and ganglion geniculi n. facialis were studied in the guinea pig labyrinth. During experimental examination, swelling up to 112% as well as shrinkage up to 35% were noticed. These volume changes do not coincide with the changes occurring in the corresponding sensory nuclei during the same stimulus. As the ganglion cells receive their impulses from various sensularies, they are responsible for several types of movement. A periodical increase and decrease of the nuclear volume are assumed to be an expression of the general total activity. The cells of the ganglion geniculi respond very strongly to these movement stimuli, which are not regarded to be adequate. Consequently it was proved that strong inadequate excitations can also influence the neighboring ganglion cells. In the cytoplasm, strong excitations lead to variations in the Nissl content. An intensive material exchange between the cytoplasm and the karyoplasm is assumed to be a cause for the changes of the nuclei volumes. But only the relation between the cell nuclei and the cell somata is altered. The volume of the whole cell remains approximately constant.
在豚鼠迷路中研究了适当刺激对前庭神经节和面神经膝状神经节的神经节细胞的影响。在实验检查期间，观察到肿胀达112%以及收缩达35%。这些体积变化与相同刺激期间相应感觉核中发生的变化不一致。由于神经节细胞从各种感受器接收冲动，它们负责几种类型的运动。核体积的周期性增加和减少被认为是总体总活动的一种表现。膝状神经节的细胞对这些不被认为是适当的运动刺激反应非常强烈。因此证明了强烈的不适当刺激也能影响邻近的神经节细胞。在细胞质中，强烈刺激导致尼氏体含量的变化。细胞质与核质之间强烈的物质交换被认为是核体积变化的一个原因。但只是细胞核与细胞体之间的关系发生了改变。整个细胞的体积大致保持不变。
