Unilateral dialysis into the ventral respiratory column of 1 mM muscimol (closed circles), an ionotropic GABA receptor agonist paradoxically increased pulmonary ventilation (V̇i; A) and breathing frequency (B) compared with dialysis of mCSF (open circles). The black line denotes when muscimol was dialyzed. *P < 0.001, comparisons with the pre DAMGO dialysis period by post hoc analysis (Holm-Sidak).
