Recent claims state that a wiring scheme as in the columnar cortical template will boost the computations performed by neural networks. We use rewiring of neural networks performing real-world cognitive tasks to study the validity of this argument. In a vast parameter and model survey we detect no indication of the proposed effect. It is on the mesoscopic, inter-columnar, scale that the existence of columns - largely irrespective of their inner organization - enhances the cortical speed of information transfer and reduces the total wiring length required to bind the distributed columnar computations towards a spatio-temporally coherent computation.
