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.
