Summary:
We use rewiring of neural networks performing real-world cognitive tasks to study whether the particular wiring observed within cortical columns is able to boost neural computation. Upon a vast survey of networks we detect no traces 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 speed of information transfer and minimizes the total wiring length required to bind the distributed columnar computations towards spatio-temporally coherent results.
