TFC distribution patterns comparison between normal and spinal injury model goat (A) and rat (B) groups.

The distribution regions of the main components were marked as “M”, the region of sub-TFC that appeared in both the normal and injury groups were marked as “S1” and “S2”, and the other small sub-TFCs in the injury group only were marked as “S3”, “S4” and “S5”. In both goats and rats, the distribution patterns of the components in the injury groups were similar to those of the normal groups, and the corresponding distribution regions of TFCs that appeared in both the normal groups and injury groups were connected with black lines. SEP: Somatosensory evoked potential; TFC: time–frequency component.
