Spatial Cohernce of Phase-Coupled Cortical Oscillations
Abstract
Abstract The goal of this research is to understand the spatial dynamics of oscillatory states of the cortex and the consequences of traveling and spiral waves in the gamma band for communication between cortical areas. This will be accomplished by analyzing data from cortical recordings and developing extended cortical models that will allow us to explore the implications of this new dynamic view of gamma oscillations. Three issues regarding phase coupling of brain oscillations will be examined here: 1) Gamma phase shifts across the cortex: What is the spatial organization of gamma oscillations across the cortical surface? 2) Dynamics in a 2-D model of interacting cortical columns. How do the spatial patterns observed in the cortex arise from interactions between neighboring cortical columns? 3) Impact of cortical feedback: How is information transmission between two cortical layers affected by the relative phases of their local gamma band oscillations?
