From: Alteration of primary afferent activity following inferior alveolar nerve transection in rats
Dark filed photomicrographs of FG-labeled TG neurons (A, B and C), the number of FG-labeled TG neurons in naive and IAN-transected rats (D) and change in the threshold intensity for eliciting escape behavior following mechanical stimulation to the mental skin reinnervated by the transected IAN (n = 5, E, F). The threshold intensity was plotted related to the stimulus intensity applied to rats face. A: naive rats, B: 7 days after IAN transection, C: 14 days after IAN transection. D: Total number of FG-labeled TG neurons in naive, 7 days and 14 days IAN-transected rats. * p < 0.05 (7 days vs. 14 days), ** p < 0.01 (vs. naive), E: ipsilateral side to IAN transection, F: contralateral side to IAN transection, before: before IAN transection. The escape threshold is shown as the medial value of the stimulus intensity. Burs in A, B and C indicate 100 μm. * p < 0.05, ** p < 0.01 (vs. before)
