Before revision:  Furthermore, we identify which regions form the strongest neurophysiological drivers of these differences in learning rate, and complement our region-based approach with a voxel-level approach to uncover structure in finer-scale responses. Finally, for a full investigation of complementary geometric approaches, we verify that quick learners develop more assortative responses to stimuli: that is, whole-brain responses that are more easily distinguishable from one another.
After revision:  Furthermore, we identify which regions form the strongest neurophysiological drivers of high dimensional patterns at both regional and voxel levels, and complete our study with a complementary test of the distinguishability of associated whole-brain responses that are more easily distinguishable from one another.
