Before revision:  The model leverages on the coincidence of top-down contextual information with bottom-up sensory flow during the training phase and on the integration of top-down predictions and bottom-up  pathways during deep-sleep-like slow oscillations  .
After revision:  The model leverages on the coincidence of top-down contextual information with bottom-up sensory flow during the training phase and on the integration of top-down predictions and bottom-up pathways during deep-sleep-like slow oscillations . Also, such mechanism hints at possible applications to artificial learning systems .
