Independent Component Analysis for Source Localization of EEG Sleep Spindle Components

Table 4

Local maxima of LORETA current source density distributions for spindle component SC3 for part C of the single-spindle timeframe. The local maxima greater than or equal to 50% of the global maximum are shown. Coordinates are in mm. Origin is at anterior commisure. For , negative values represent left; positive values represent right. For , negative values represent posterior; positive values represent anterior. For , negative values represent inferior; positive values represent superior. Brodmann areas (BA) and both descriptions of the anatomical regions are shown.
