Repeated movie viewings produce similar local activity patterns but different network configurations
We examine network re-organization when people view the same movies in repeated presentations. We find the brain's functional configurations adapt not only by the strength of individual connections but by topological organization.

Global features of functional brain networks change with contextual disorder
We examined global features of whole-brain functional connectivity to inputs with varying disorder. Modularity, module numbers, and partition similarity varied with input disorder. Default-mode and sensory brain regions were least impacted by the manipulation.

Classification of inter-subject fMRI data based on graph kernels
We used a method based on graph kernels to discriminate two types of auditory stimuli in fMRI data. We show that the discriminating information comes from topological features of the graphs and from relational pattersn in the neighborhood of each node. In addition, we examine two different ways to represent graphs, as well as the influence of noisy connections in our graphs along with a possible way to alleviate their impact.
