Abstract
In voltage clamped photoreceptor cells of the barnacle, light-induced membrane current varied nonlinearly with membrane potential and changed sign at about + 27 millivolts (reversal potential) independently of light intensity. Instantaneous current-voltage relations were linear and intersected the voltage axis at the reversal potential. Illumination increased membrane conductance that was dependent on membrane potential, light intensity, and time.
摘要
在藤壶的电压钳制光感受器细胞中，光诱导的膜电流随膜电位呈非线性变化，且在约 +27 毫伏（反转电位）处改变符号，与光强度无关。瞬时电流 - 电压关系呈线性，并在反转电位处与电压轴相交。光照增加了依赖于膜电位、光强度和时间的膜电导。
