The Corticospinal Discrepancy: Where are all the Slow Pyramidal Tract Neurons?

Alexander Kraskov1, Stuart Baker2, Demetris Soteropoulos2, Peter Kirkwood1, Roger Lemon1.   

Abstract

This feature article focuses on the discrepancy between the distribution of axon diameters within the primate corticospinal tract, determined neuroanatomically, and the distribution of axonal conduction velocities within the same tract, determined electrophysiologically. We point out the importance of resolving this discrepancy for a complete understanding of corticospinal functions, and discuss the various explanations for the mismatch between anatomy and physiology.
