(A) A whole-brain voxel-wise linear mixed effects regression was performed in12, which revealed a vmPFC region that showed a significant interaction between learning block and problem complexity. Neural compression increased over learning blocks and was higher for learning problems with fewer relevant dimensions (each fMRI run consists of four learning blocks; see the original paper for more details). (B) Functional correspondence between the clustering module of the controller-peripheral system and vmPFC in the human brain. The clustering module deploys attention strategies (in terms of attention compression) that track the degree of neural compression in vmPFC across category learning tasks over learning across category structure complexity.
