Contralateral Metabolic Activation Related to Plastic Changes in the Spinal Cord after Peripheral Nerve Injury in Rats

Figure 3

Representative pseudocolor-enhanced images showing metabolic activities in the L3 lumbar spinal cord of control (a) and neuropathic (b) rats after peripheral stimulation. The right side of the spinal cord is ipsilateral to the electrical stimulation of the hind paw. Note the increased 2-DG uptake in the contralateral ventral horn of the neuropathic rat compared to the ipsilateral ventral horn. On the contrary, 2-DG uptake increased in the ipsilateral ventral horn of the control rat compared to the contralateral ventral horn.
