Figure 4.
Complex monoamine release profiles observed during trials with delayed MLR-evoked locomotion. Profiles recorded at various locations within the L5 spinal segment from a single experiment. Gray bars indicate the period of MLR stimulation (left side, 130 μA throughout, 20 Hz, 1 ms duration). Locomotor activity is indicated by ENG recordings from right (R) and left (L) nerves. Calibration bars: 10 s. SMAB: semimembranosus/anterior biceps. Figure format and abbreviations as in Figure 3.
