Fig. 4From: Neurophysiological assessment of spinal cord injuries in dogs using somatosensory and motor evoked potentialsMotor evoked potential recordings (MEPs) in a dog presenting with thoracolumbar spinal injury. Tracings obtained following left (a) and right (b) extensor carpi radialis and left (c) and right (d) cranial tibial muscle stimulation. MEP capture in a, b and c and absence in d is consistent with right-sided spinal lesion. Latency (ms; vertical bar) and peak-to-peak amplitude (µV) measurements are displayed. Gain = 100 µV/div (a, b) or 15 µV/div (c, d); sweep speed = 15 ms/divBack to article page
