the matrix will have a value. In an attempt to study biologically significant functional relationships, correlations above a given value may be labeled as connections or edges (see Dosenbach et al. 2007 and Fair et al. 2007 for examples). However, it should be noted that no one threshold is the “right” one and interpretations should be based on findings that are consistent across multiple thresholds. This regional matrix produced can rightly be described as a network since it describes a distinct set of nodes with defined connections or edges between them.
