The determination of trigger features of single neurons in afferent pathways has been one of the central problems in sensory physiology. A novel method, called Alopex, has been developed, in which response feedback is used to construct visual patterns that optimize the responses. Data are presented which show the emergence of trigger features of cells monitored in frog visual tectum. The method id checked against results obtained by scanning the visual field with a small spot. Correlations between Alopex pattern and scann patterns are generally between 0.3 and 0.5 but may be as high as 0.9 when smoothing and/or averaging procedures are applied to the Alopex patterns. The dynamics of the Alopex process are discussed and details of the algorithms are presented. The series of experiments presented here has established the validity of the method and suggests that this approach should find wide application in receptive field studies. For that purpose data on the instrumentation and software are also presented.
确定传入神经通路中单个神经元的触发特征一直是感觉生理学的核心问题之一。一种名为Alopex的新方法已被开发出来，该方法利用反应反馈来构建优化反应的视觉模式。文中给出的数据显示了在青蛙视顶盖中监测到的细胞触发特征的出现。该方法与用小点扫描视野所获得的结果进行了核对。Alopex模式与扫描模式之间的相关性一般在0.3到0.5之间，但当对Alopex模式应用平滑和/或平均程序时，相关性可能高达0.9。文中讨论了Alopex过程的动力学，并给出了算法细节。这里展示的一系列实验证实了该方法的有效性，并表明这种方法在感受野研究中应会有广泛应用。为此，还给出了关于仪器和软件的数据。
