Before revision:  Such effects favour higher performances in retrieval and classification tasks and create hierarchies of categories in integrated representations. The model leverages on the interaction between of top-down cortico-thalamic predictions and bottom-up thalamo-cortical projections during deep-sleep-like slow oscillations  .
