Independent Component Analysis for Source Localization of EEG Sleep Spindle Components

Table 2

Local maxima of LORETA current source density distributions for spindle component SC1 for part A 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 at anterior commisure. For 𝑋, negative values represent left; positive values represent right. For 𝑌, negative values represent posterior, positive values represent anterior. For 𝑍, negative values represent inferior, positive values represent superior. Brodmann areas (BA) and both descriptions of the anatomical regions are shown.
