Before revision:  We find that quick learners develop both higher dimensional and more compact responses to stimuli than slow learners, suggesting a greater efficiency in embedding rich patterns of information. Using a virtual lesioning approach ,  we identify which regions form the strongest neurophysiological drivers of these differences in learning rate .
