The retraction of the article “AREAL DIFFERENCES IN DIAMETER AND LENGTH OF CORTICOFUGAL PROJECTIONS (Cereb. Cortex (2011) first published online August 8, 2011 doi:10.1093/cercor/bhr183) was initiated by the authors, motivated by the legitimate suspicion that the thickness of the sections, instead of 60 μm was 34 μm, was due to a recently discovered malfunction of the microtome. Two of the collaborating laboratories are currently, independently, proceeding to verifications. If the malfunction were to be confirmed, the lengths of some of the pathways, those with pronounced anteroposterior trajectories, in particular those originating from striate and extrastriate areas, would have to be corrected. The computed transmission delays would need correcting as well. The new version will be re-reviewed by the original referees.
