结论1.在正常狗中可以形成一种固定元音的听觉模式，这种模式相对于某些参数的变化是不变的，这些参数包括基本频率、强度和呈现的持续时间（300-75毫秒）。两个公式足以识别元音[a]和[i]。2.元音[a]和[i]的听觉模式在去除听觉投射皮层后，保留了原始元音，并且在初步去除听觉皮层后，原始元音可以在动物体内形成。3.初步去除听觉皮层后，动物对元音的识别受到干扰，刺激减少（共振峰的数量减少并且刺激呈现的持续时间缩短）。
Conclusions1.An auditory pattern of a stationary vowel, invariant relative to changes in certain parameters — the basic frequency, intensity, and duration of presentation (300-75 msec)-can be formed in intact dogs. Two formulas are sufficient for identification of the vowels [a] and [i].2.The auditory pattern of the vowels [a] and [i] is preserved after bilatal removal of the auditory projection cortex and it can be formed in animals after preliminary removal of the auditory cortex.3.The identification of vowels by animals after preliminary removal of the auditory cortex is disturbed when the excessiveness of information contained in the stimuli is reduced (the number of formants is reduced and the duration of stimulus presentation is short-ened).
