Legends for supplemental figures and movies

Supplemental figure 1. Effects of low concentration of adrenaline on a pre-inspiratory neuron activity in wild-type mice. A, Membrane potential trajectory of a pre-inspiratory neuron in a postnatal day 0 wild-type mouse in control solution (without adrenaline). B, Activity in the presence of 0.2 μM adrenaline. Note the more regular pre-inspiratory neuron burst pattern and C4 activity in B. Vm, membrane potential trajectory; C4, C4 inspiratory activity.

Supplemental figure 2. Respiration-related nerve activity in wild-type mice. A, Facial nerve, C4 and L1 activities in an embryonic day 18.5 wild-type mouse in control solution (without adrenaline). A', Faster sweep representation of nerve activity at the black bar in A. B, Averaged nerve activity triggered by C4 (10 cycles). Note that the respiration-related nerve activity is irregular, and the pre-inspiratory activity in the facial nerve and L1 recordings is not clear. VII, facial nerve activity; C4, C4 inspiratory activity; L1, first lumbar ventral root activity.

Supplemental movie 1. Optical recording of inspiratory neuron activity in the ventral medulla of Atp1a2−/− mice in Fig. 6A. Results are the average of 40 respiratory cycles triggered by C4 inspiratory activity.

Supplemental movie 2. Optical recording of non-inspiratory burst neuron activity in the ventral medulla of Atp1a2−/− mice in Fig. 6B. Results are the average of 30 bursts triggered by an initial spike of unit discharge recorded extracellularly with a glass electrode.
