提出一个高层听觉神经系统的计算模型。模型实现了对内侧膝状体和听觉皮层的模拟。在内侧膝状体计算模型中,具体模拟了听觉系统的两条上行通路,其中一条是拓扑的、不可塑的,另一条是非拓扑、可塑的。在听觉皮层计算模型中,构造了多层拓扑自组织网络和复杂序列检测网络,模拟并实现了听觉皮层的等频率带、功能柱、复杂特征检测器和短时记忆等多种结构和功能。
A computational model of the auditory nervous system in high-level is proposed. The model realizes the simulation of medial geniculate body and auditory cortex. In the medial geniculate body computing model, two uplink paths of the auditory system are simulated in detail, one of them is topological and non-plastic, and the other is non-topological and plastic. In the auditory cortex calculation model, a multi-layer topological self-organizing network and a complex sequence detection network are constructed, and various structures and functions of the auditory cortex such as equal frequency bands, function columns, complex feature detectors and short-term memory are simulated and implemented.
