Little is known about how the size of tract can modify the speed of conduction. Larger tract volumes could depend on a number of factors, including greater fibre myelination, higher number of axons and larger axonal diameter. Experimental physiology has shown that the conduction speed of larger diameter, or more myelinated axons is faster. A higher number of axons would also boost the speed of conduction by assuring a parallel processing. So, are larger pathways faster ?
