Figure 2: Main effects of massage on a peripheral nerve injury rat. Regions of somatosensory cortex that differed in amplitude of low-frequency fluctuation value among the four groups (normal, model, sham massage, and massage groups). The red clusters in the left somatosensory cortex (blue area) were significantly different among the four groups located. The others red points did not pass the multiple comparison tests. The green numbers are coordinates referenced to a stereotaxic magnetic resonance imaging template of the rat brain.
