Evoked electrical potentials were recorded via intracerebral electrodes in a patient with stump and phantom limb pain who had a previously implanted dorsal column stimulator. When pain was elicited by peripheral stimulation it was found that positive deflections appeared in the ventrolateral nucleus of the thalamus at time latencies corresponding to the propagation velocities of A delta- and C-fibres. Dorsal column stimulation completely eliminated the C-fibres. Dorsal column stimulation completely eliminated the C-fibre deflection and partially eliminated the A delta-fibre deflection.
通过脑内电极记录了一名患有残肢和幻肢痛且先前已植入背柱刺激器的患者的诱发电位。当通过外周刺激引发疼痛时，发现在丘脑腹外侧核出现正向偏转，其时间潜伏期与Aδ纤维和C纤维的传导速度相对应。背柱刺激完全消除了C纤维。背柱刺激完全消除了C纤维偏转，并部分消除了Aδ纤维偏转。
