The behaviour of the sensory- and the ganglia cells in response to inadequate stimuli was studied at 12 adult guinea pigs. The sensory cells of the three Cristae ampullares dont respond remarkably to acoustic stimulation. At the range of 1000 Hz a recognizable increase in the size of the sensory cells at the upper ampulle was noticed. Of no account was the rest of the volume variations. At the range of 5000 Hz the sensory cells of the Maculae staticae responded with a considerable increase in the size of their sensory nuclei up to 38%. The cells of the Ganglion vestibulare react upon acoustic stimulation throughout with an increase in their nuclei up to between 16% and 54%. It was noticed that the volume enlargement increases from the lower to the higher frequencys. The cells of the Ganglion geniculi nervi facialis react upon acoustic impulses too with an increase in their nuclear volume. In low tone acoustic range and in high tone acoustic range the growth rates are more than 50% beyond the standard. Thos cells respond to frequency of 1000 Hz remarkably intensive. It was noticed that the maximum volume increase of their nuclei was in the average up to 103%. All the sensory and ganglia cells react upon rinsing the external auditory canal with 12 degrees C water, with a shrinkage of their nuclei. Besides that the sensory cells of the Cristae and the Maculae show a volume decrease between 8% and 19%. The cells of the Ganglion vestibulare et geniculi respond with a considerable volume decrease of their nuclei from 32 to 41% under the average.
对12只成年豚鼠的感觉细胞和神经节细胞对不适当刺激的反应进行了研究。三个壶腹嵴的感觉细胞对声刺激没有明显反应。在1000Hz范围内，注意到上壶腹的感觉细胞大小有明显增加。其余的体积变化则无关紧要。在5000Hz范围内，椭圆囊斑的感觉细胞对声刺激的反应是其感觉核大小显著增加，高达38%。前庭神经节细胞对声刺激的反应是其细胞核始终增大，增幅在16%至54%之间。注意到体积增大从低频到高频逐渐增加。面神经膝状神经节细胞对声脉冲也有反应，其核体积增加。在低音和高音声范围内，生长率超过标准的50%以上。这些细胞对1000Hz的频率反应非常强烈。注意到它们细胞核的最大体积增加平均高达103%。用12℃水冲洗外耳道时，所有感觉细胞和神经节细胞的细胞核都会收缩。除此之外，壶腹嵴和椭圆囊斑的感觉细胞体积减少8%至19%。前庭神经节和膝状神经节细胞的细胞核体积显著减少，平均减少32%至41%。
