Figure S16 - Isotropy
DESCRIPTION:
Estimating the isotropy to examine cortical variation in the shape of thalamic connectivity patterns. (A) Isotropy of ipsilateral
thalamic connections was calculated for each cortical parcel for 100 thresholds. Two examplar parcels (PHT, magenta; 6r, cyan) are
shown. Cooler colors reflect more isotropic connectivity patterns (the connectivity pattern evenly extends in x, y, and z directions),
while warmer colors reflect more anisotropic connectivity patterns (e.g., does not extend evenly in x, y, and z directions).. PCA was performed using the matrix in panel A, resulting in a single value for each cortical parcel (Isotropypc1 loadings). Cooler colors reflect cortical parcels with more isotropic thalamic connectivity patterns, while warmer colors reflect cortical parcels with more anisotropic thalamic connectivity patterns.
