Interareal pathways come in two flavors. Feedforward and feedback pathways linking cortical areas form dual counter streams where combinatorial distance rules determine a hierarchical organization. In contrast to the infragranular layers, supragranular layers exhibit point-to-point topology in both feedforward and feedback pathways. These findings have important consequences for understanding interareal processing.
