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

Figure 4

Comparison between cross ratios at different lumbar levels of the spinal cord in normal and neuropathic rats following electrical stimulation of the paw. Cross ratios were calculated as follows: [metabolic activity in the contralateral ventral horn]/[metabolic activity in the ipsilateral ventral horn] × 100 (Control: control rats, Injured: neuropathic rats). Asterisks () indicate significant differences between cross ratios at different lumbar levels of the spinal cord in normal and neuropathic rats, according to the independent t-test (, ).
