+## correlation_matrices
|
|
|
+
|
|
|
+Correlation matrices are fully preprocessed and stored in the variable 'corrmat' within respective .mat files:
|
|
|
+Males: Nuisance regression (linear & quadratic trends + 6 rigid-body motion parameters + 1st 5 PC's of CSF signals + body temperature + respiratory rate + isoflurane dosage) -> bandpass filtering [0.008, 0.10 Hz])
|
|
|
+Females: Nuisance regression (linear + quadratic trends, 6 rigid-body motion parameters, 1st 5 PC's of CSF signals) -> bandpass filtering [0.008, 0.10 Hz])

|
|
|
+mirrored_groupwise_template.nii = the right hemisphere of our 'GroupwiseTemplate.nii' mirrored across the midline to create a symmetrical brain template for voxel-mirrored homotopic connectivity (VMHC) analyses

|
|
+voxelwise_homotopy_tstats.nii = image of t-statistics testing voxel-wise homotopy across the 19 male scans
|
