A numerical thought experiment was conducted to assess whether stimulus-specific, short-term changes in auditory neural responsiveness could explain the formation of auditory objects underlying the auditory continuity illusion. A tonotopic, two-layer feedforward network model with one time constant for synaptic weight augmentation based on firing rate, and an independent time constant for synaptic weight decay was presented with classical continuity illusion stimuli. The results suggest that the continuity illusion could, in principle, be explained by basic, duration-dependent auditory circuit behavior, which could emerge at either early or later stages of processing.
进行了数值思维实验，以评估听觉神经反应的刺激特异性、短期变化是否可以解释听觉连续性错觉所基于的听觉对象的形成。提出了一个具有一个时间常数的音位拓扑、两层前馈网络模型，用于根据发放率增强突触权重，以及用于突触权重衰减的独立时间常数。结果表明，连续性错觉原则上可以用基本的、依赖于持续时间的听觉电路行为来解释，这种行为可能出现在处理的早期或晚期阶段。
