Figure 2

Maxillary nerve electrical properties in monkeys. Multiple-unit recording was performed for a nerve fiber bundle of the maxillary nerve in five monkeys with MNC. (A) A representative trace of multiple-unit recording. The black bars underneath the recording denote stimulation to the receptive field. The stimulus conditions were with von Frey filaments of 8, 10, 15, 26, and 60 g nominal force for 5-sec duration. (B) Firing rate of maxillary nerve fibers. In animals #1 and #2 only the contralateral side of the maxillary nerve was successfully recorded, while in animals #3 and #4 bilateral recording was achieved. The horizontal axis of each panel denotes the von Frey filament nominal force (in grams) that was applied to the receptive field of the maxillary nerve fibers being recorded. The maximum forge applied was 60 g. Results for each nerve fiber bundle were normalized to the data at the maximum stimulus. Open circles: firing rate data from the contralateral side of the maxillary nerve. Closed squares: firing rate data from the ipsilateral side of the maxillary nerve with MNC.
