Average velocity of initial-spike propagation was calculated by fitting lines to the maximum latency data of each slice, plotted as distance traveled versus time. The reciprocal of the slope for the fitted line equals the conduction velocity in μm/ms ± SE. Intralaminar plots were divided into lateral and medial directions so that lines could be fitted in each direction.
