Abstract
The ocellar potential (OP) of planaria was recorded using microelectrode techniques. The action spectrum and spectral sensitivity of the OP are described. Maximum OP sensitivity was found with 508 nm light. A moderate increase in sensitivity to blue light was observed. This is typical of many invertebrate photoreceptors and was shown, by selective chromatic adaptation, not to indicate the presence of a second pigment.
摘要
使用微电极技术记录了涡虫的眼点电位（OP）。描述了OP的作用光谱和光谱敏感性。发现508nm光下OP敏感性最高。观察到对蓝光的敏感性有适度增加。这是许多无脊椎动物光感受器的典型特征，并且通过选择性颜色适应表明，这并不意味着存在第二种色素。
