Figure 8. PSPs evoked by PT stimulation after a DLF lesion.

Figure 8

In all panels, except J, upper traces are intracellular records from two motoneurons (A-H and K, L, M, N, O respectively) and lower traces are from the cord dorsum in the L2 segment, with the same format as in Figs. 3 and 5. All these records were obtained after a lesion of the dorsolateral part of the left lateral funiculus (DLF) in the rostral half of the C3 segment. A reconstruction of this lesion is shown in I. J, Cord dorsum potentials recorded in the C4 segment, evoked by stimuli applied in the co PT before (black) and after (grey) the lesion. The difference between these potentials is shown to the right. Note that EPSPs were evoked as efficiently from the contralateral (co) PT as from the ipsilateral (i) PT (and at the same latencies) but IPSPs required a longer train of stimuli (and were evoked at longer latencies, i.e. less efficiently).
