Table 1.

The table of abbreviations for various subsets and transformations of component spatial maps. Masks have 0s and 1s for voxels’ values, while non-mask options comprise a subset of original voxels, with their original Z-statistics.

Abbreviation	Description
m	IC’s spatial map
ma	Absolute value of m, i.e., |m|
mp	The positive voxels of m
mn	The negative voxels of m
${\mathbf{m}}_p^b$	The mask for positive voxels of m
${\mathbf{m}}_n^b$	The mask for negative voxels of m
${\mathbf{m}}_p^{\tau }$	The voxels in m that are bigger than τ
${\mathbf{m}}_n^{\tau }$	The voxels in m that are smaller than −τ
${\mathbf{m}}_p^{\tau ,b}$	The mask for voxels that are bigger than threshold τ
${\mathbf{m}}_n^{\tau ,b}$	The mask for voxels that are smaller than threshold −τ
