Methods to estimate peripheral propriospinally mediated excitation of lumbar motoneurones. Group I and group II afferents from tibialis anterior (TA) activate propriospinal neurones (PN) projecting to quadriceps (Q) motoneurones (MN). The early peak has a low threshold and is elicited by group I afferents (grey area), whereas the late peak has a higher threshold and is due to group II afferents (see Chapter 7). The difference between the afferent conduction times of Ia volleys in femoral (FN) and CP nerves was 5. The zero central delay (arrow and dotted vertical line) corresponds to the 33. As in the cervical observed after stimulation of afferents from virtu- enlargement, the excitation mediated through this ally any leg or thigh muscle, including antagonists pathway also differs from a segmentally mediated (cf.
