Abstract

Elaboration of differential instrumental conditioned reflexes in rabbits showed that probabilities of responses to differential stimuli were inversely related to differences in intensity between conditioned and differential stimuli. Factor analysis of a response probability matrix revealed two orthogonal axes. They could be interpreted as the axes of brightness and darkness in achromatic space of a rabbit. Lights of different intensities were located on a semicircle in accordance with their intensities. The experiments imply that light intensities are coded by excitation vectors composed of responses of brightness and darkness neurons.

摘要

对兔子进行的差异工具性条件反射实验表明，对差异刺激的反应概率与条件刺激和差异刺激之间的强度差异呈负相关。对反应概率矩阵进行因子分析揭示了两个正交轴。它们可被解释为兔子消色差空间中的亮度轴和暗度轴。不同强度的光根据其强度位于一个半圆上。这些实验表明，光强度是由亮度神经元和暗度神经元的反应组成的兴奋向量编码的。
