The ability of the auditory organ to resolve brief changes in an acoustic signal presented either monaurally or binaurally is not only of great importance in the processing of speech, it is also involved in the localization of sound stimuli and in selective listening. In the latter context, the electric activity of the primary auditory cortical projection field AI of the cat has been studied with the aim of evaluating specific response patterns evoked by brief changes in interaural time difference. The differences in response of the neuron populations sampled by two recording electrodes indicate that, within this area, there are significant differences in temporal resolution ability. Whereas click stimuli elicit distinct potential patterns at the two sites, with a brief change in interaural time difference, a marked response is recorded by only one of the electrodes. This response is characterized by a decrease in amplitude as the interaural time difference is reduced and as the duration of the time-shift stimulus decreases.
听觉器官分辨单耳或双耳呈现的声音信号中短暂变化的能力，不仅在语音处理中非常重要，还参与声音刺激的定位和选择性听觉。在后一种情况下，为了评估由双耳时间差的短暂变化引起的特定反应模式，对猫的初级听觉皮层投射区AI的电活动进行了研究。两个记录电极采样的神经元群体的反应差异表明，在该区域内，时间分辨能力存在显著差异。当点击刺激在两个部位引发不同的电位模式时，随着双耳时间差的短暂变化，只有一个电极记录到明显的反应。这种反应的特征是，随着双耳时间差减小以及时移刺激持续时间缩短，振幅降低。
