fmri_mirror

Description

FMRI_MIRROR Flips a vectorized brain map left-to-right (sagittal mirror). Flips the brain image along the x-axis (left-right) to produce its mirror image. Useful for testing laterality or creating symmetric averages (hemisphere-averaged FC maps, etc.).

Usage

d2 = fmri_mirror(d)

Inputs

  • D: Vectorized brain data (228453 x N) or volume (91 x 109 x 91 x N).

Outputs

  • D2: Mirror-flipped brain, same format as D.

Examples

d_mirror = fmri_mirror(d);
bilateral = (d + fmri_mirror(d)) / 2;   % bilateral average
