Values are means ± SD. Note that the f–I slope was obtained for all recorded motoneurons (a criterion for the inclusion), whereas the other parameters were not obtained for all motoneurons. The AHPd could be measured in 20 motoneurons, whereas the AHP2/3 was measured in an additional 18 motoneurons. From the relation between the AHPd and AHP2/3 in those 20 motoneurons [AHPd = 1.8(AHP2/3) + 18 ms; see text], it was possible to estimate the AHPd for the remaining 18 motoneurons (“AHPd calculated”).
