这项工作是一项研究的影响，不同的内部和相互连接的参数集总模型的丘脑皮层电路设计模拟事件相关的局灶性ERD/环绕ERS内的α波段。我们首先验证现有的ERDIERS模型。然后，我们改变模型中的抑制性和兴奋性连接参数。我们观察到，ERD和ERS表现出不同的特点，不同的连接。此外，α频带中的功率含量的变化与参数值的变化成正比。我们建议验证模型与相关的实验数据作为当前工作的延续。
This work is a study of the effects of varying intra- and inter-connectivity parameters in a lumped model of the thalamocortical circuitry designed to simulate event-related focal-ERD/surround-ERS within the alpha band. We start by validating an existing ERDIERS model. We then vary the inhibitory as well as excitatory connectivity parameters in the model. We observe that the ERD and ERS show different characteristics with varying connectivity. Furthermore, variation of power content in the alpha band is directly proportional to the variation in the parameter values. We propose to validate the model with relevant experimental data as a continuation of the current work.
