There is a site- dependent effect on pulmonary ventilation (V̇I; A) and breathing frequency (B) of unilateral dialysis of 50 mM atropine as dialysis into the hypoglossal motor nuclei did not (P = 0.905) alter V̇I and breathing frequency which contrast to the marked hyperpnea after atropine dialysis into the ventral respiratory column (Fig. 1). The black line denotes when atropine was dialyzed.
