Fig. 2From: TRPM8-mediated cutaneous stimulation modulates motor neuron activity during treadmill stepping in miceRepresentative images of the spinal cord ventral horn of each group immunostained with c-fos (green) and ChAT (red) are shown for the sedentary, sedentary + icilin, low-speed stepping, high-speed stepping, and low-speed stepping + icilin groups. C-fos merged in the nuclei of ChAT-positive soma in lamina IX indicates activated (c-fos+) MN (white arrowheads). Scale bar = 100 μm (color figure online)Back to article page
