Summary:
Functional networks describe the dependence of spatially distributed areas of the brain based on temporal correlations. In this paper, we discuss how functional networks generated from the time series of voxels in an fMRI experiment vary over time in response to a periodic retinotopic stimulation. Since functional connectivity studies only consider the entire experimental time series, there is usually only a single network constructed for each experiment and subject. Our goal is to investigate how the statistical properties of functional networks vary during an experiment and the relationship between the complex network measures.
