Figure 3. Acidic saline injections produce long lasting changes in many of the electrophysiological properties of NVmes cells innervating masseter muscle spindles.

Means ± S.E. of twelve electrical properties are shown for Control (filled circle) and Experimental (open circle) neurons recorded at 7 time periods after the second intramuscular injection. *, p<0.05 for simple contrasts. In panels F, G and J, all ps<0.01.
