Fig. 5. (A) Stage-dependent changes in fictive lung burst frequency during bath
application of the
2-adrenoceptor agonist clonidine (Clo; 25
µmol l–1). (B,C) The effects of Clo application on lung
burst frequency in the presence of the GABAA/glycine antagonist
mixture (bicuculline 1.25 µmol l–1/strychnine 1.5 µmol
l–1) in (B) the pre-metamorphic and (C) adult groups
(N=6, each group). Values are means ± s.e.m.
*Values statistically different from baseline at
P<0.05;
value statistically different from
corresponding mixture value at P<0.05.
