Abstract

Following stimulation with NaCl of different concentrations, responses from one, two or three receptor cells of the sensillae could be recorded, one of them being always "dominant". The other one or two secondary cells showed a lower frequency and a faster adaptation. The responses of the dominant cells proved to be variable, even to repeated stimulations using the same concentration of the same substance. Increasing the concentration from 0.01 mol/l to 1.0 mol/l, the initial frequency may increase or decrease, however, frequency minimum or maximum may also occur at an intermediate concentration. These findings indicate a less specialized stage of the receptor cells. The individual characteristics of the receptor cells may be surpassed when averaging the responses of sufficiently high number of cells.

迁移蝗上颌触须化学感受器的电生理研究。NaCl刺激下感受器反应的一般特征。
在不同浓度的NaCl刺激下,可以记录到一个、两个或三个感受器细胞的反应,其中一个细胞总是“占优势”。另外一个或两个次生细胞的频率较低,适应速度较快。优势细胞的反应被证明是可变的,甚至对使用相同浓度的相同物质的重复刺激也是如此。当浓度从0.01 mol/l增加到1.0 mol/l时,初始频率可能升高或降低,但在中间浓度时也可能出现频率最小或最大值。这些发现表明受体细胞的特化程度较低。当对足够多的细胞的反应取平均值时,可能会超过受体细胞的个体特征。
