Fig. 9. The effects of L-glutamate (L-Glu) iontophoresis in
the dorsal posterior (DP) and precommand nuclei (PCN) before and after
bicuculline methiodide (BMI) iontophoresis on the coefficient of variation
(CV) in electromotor neuron (EMN) interval (A), the minimum EMN interval (B),
and the maximum EMN interval (C). Values shown are means ±
S.E.M. Asterisks represent statistically
significant differences (MannWhitney U test;
P<0.05).
