Method In these studies, values were obtained by the method of antidromic activation, whereby action potentials are initiated by electrical stimulation of the axon, and the latency of the conducted spike is recorded near the cell body. All of the measures shown in Table 1 were taken from adult subjects. Developmental changes in the composition of central and peripheral axon pathways can be considerable (e.g., Foster et al., 1982 Yates and Juraska, 2007), and it is important to control for age when comparing the properties of different axonal pathways.
Comments "Table 1 gives values for axonal conduction times measured in a selection of long range axonal systems in the brains of rodents, rabbits, cats and monkeys (representing four mammalian orders)...Some axonal systems are very rapidly conducting, some are very slowly conducting, and some are characterized by a great diversity in axonal conduction delays."
