Fig. 8. (A) One example each of the effects of bicuculline methiodide (BMI)
iontophoresis in the dorsal posterior (DP) and precommand nuclei (PCN), and
the effects of L-glutamate (L-Glu) iontophoresis
immediately before and immediately after BMI iontophoresis. L-Glu
iontophoretic currents consisted of 1 µA for 20 s, while BMI
iontophoretic currents consisted of +100 nA for 4 min, each of which is shown
as a horizontal bar beneath each column. (B) Excerpts from A of examples of
different burst types occurring during BMI iontophoresis in DP and PCN. (C)
Number of different burst types induced by BMI iontophoresis in DP and PCN.
Values shown are means ± S.E.M. There
were no significant differences in the numbers of any of the three burst
types.
