Figure 3.Trigeminal nerve electrical stimulation (TNS) relieves tissue damage and neuronal degeneration. (A) Representative hematoxylin-eosin staining images of four groups of cortical tissues showing areas of necrosis, scale = 50 μm. (B) Representative Nissl staining of four groups of cortical tissues demonstrates necrotic degeneration of neurons, scale = 20 μm.
