我们引入了惯性神经滤波器(iDNF)模型,这是动态神经滤波器(DNF)模型的扩展,该模型产生类似于在蝗虫触角叶(al)中观察到的时空模式。在以前的工作中描述的DNF模型包括一个时间尺度,定义了模型固有的离散动力学。它缺乏生物时空数据中存在的第二种、缓慢的时间尺度,在这种尺度下,人们发现单个神经元对气味的反应是缓慢的时间模式。利用iDNF,我们研究了导致时间有序时空模式的机制,类似于在实验数据中观察到的。我们的结论是,在演化的时空格局中,第二个时间尺度对于时间秩序的创建至关重要。
We introduce the inertial-DNF (iDNF) model, an expansion of the dynamic neural filter (DNF) model, a model generating spatiotemporal patterns similar to those observed in the locust antennal lobes (ALs). The DNF model, which was described in previous works, includes one temporal scale defining the discrete dynamics inherent to the model. It lacks a second, slow, temporal scale that exists in the biological spatiotemporal data, where one finds slow temporal patterns of individual neurons in response to odor. Using the iDNF, we examine mechanisms that lead to temporal ordered spatiotemporal patterns, similar to those observed in the experimental data. We conclude that a second temporal scale is crucial for the creation of temporal order within the evolving spatiotemporal pattern.
