Resumen:

In order to analyze brain functional connectivity (FC) in humans, this work focuses on resting state functional magnetic resonance imaging (Rs-fMRI) studies to measure functional connectivity within default-mode network (DMN). The objective of the present study is to compare functional connectivity networks in healthy subjects with a drug-refractory epilepsy patient. Since the FC has a dynamic nature, evidence of variations over time and pathology are explored. The FC graph in Rs was obtained using the visibility algorithm. Based on the resulting graph, it was possible to determine how each voxel is connected to others and it is also possible to identify the hubs in healthy subjects and compare them with the DMN and how connectivity networks are altered in epilepsy patients.
