SCENE:
Subcortical results

DESCRIPTION:
This scene contains subcortical visualizations of the two neural signatures and the neural representation of the latent aesthetic space.

Neural signature of the visual semantics dimension (SFig. 10a): AATr_predictPC1_FS4_10k_weights_Zvalue.dscalar.nii

Neural signature of the hedonic value dimension (SFig. 10b): AATr_predictPC2_FS4_10k_weights_Zvalue.dscalar.nii

For subcortical regions, we used the Scale IV parcellation (54 regions) from the Melbourne Subcortex Atlas to extract regional activity patterns (SFig. 14). Dissimilarity matrices were quantified using the Pearson correlation distance (1 − r) and correlated with the target RDM (pairwise Euclidean distances of images in the two-dimensional aesthetic space) using Spearman's rho:
RSA_subcortical_TianV4_tvalue.dscalar.nii

Results were validated using alternative distance measures (Mahalanobis distance and Euclidean distance based on z-normalised dimensional scores):
RSA_subcortical_Mahalanobis_TianV4_tvalue.dscalar.nii
RSA_subcortical_Zscore_Euclidean_TianV4_tvalue.dscalar.nii
