Table 5

Sorted ICs , for SSTA data showing self-NEs contributing to the ICA contrast function (2nd column), NE components (3rd column), and loading factors (), of the leading ICs on the PC basis. Loading factors, sorted by absolute value, explaining up to 85% of the unitary norm are in bold font. The last two columns give the skewness and kurtosis of ICs.
