S4 - Alternative methods for calculating spatial extent of streamline counts
DESCRIPTION:
Comparison between EDpc1 loadings and alternative measures to quantify the extent of cortical connections within the
thalamus.
(A) EDpc1 score cortical map (left) and comparison with EDpc1 loadings (middle) and ED values at individual thresholds
(right). PCA was applied to the transposed ED matrix (Fig. 1C) and explained 64% of the variance.
(B) Mean ED cortical map,
calculated by averaging ED across thresholds for each cortical parcel.
(C) Weighted Mean ED cortical map, calculated by weighting
thresholds and calculating the ED across thresholds.
(D) Streamline count (SC) Skewness cortical map, calculated as the standardized
difference between mean and median SC values across the thalamus.
(E) Weighted Nuclei SC cortical map, calculated by multiplying
Mean SC for each cortical parcel with the corresponding thalamic nucleus’s volume.
