本文观察了清醒猕猴颞叶下皮层神经元对单一刺激和成对刺激的反应。大多数神经元对成对刺激的反应弱于对单独呈现的最佳单一刺激的反应。这种“抑制由第二个刺激”没有出现刺激选择性和抑制更大的时候，第二个刺激出现在感受野的位置，表现出较弱的反应。这种现象表明IT神经元之间的竞争性相互作用可能涉及视觉注意或学习或两者兼而有之。
The responses of neurons, in inferior temporal cortex of the awake macaque, to single stimuli and pairs of stimuli were examined. The responses of most neurons were weaker to pairs of stimuli than to the best single stimulus of that pair presented alone. This 'suppression by a second stimulus' did not appear to be stimulus-selective and the suppression was greater when the second stimulus appeared in receptive field locations that exhibited weaker responses. This phenomenon suggests competitive interactions between IT neurons that may be involved in visual attention or learning or both.
