Scoring: “0”: 0–1 neuron identified; “1”: 2–5 neurons identified. The numbers in black represents a weak labelling pattern. “2”: 6–10 neurons identified. The numbers in green represents a median labelling pattern. “3”: >10 neurons identified. The numbers in red represents a strong labelling pattern. Highlighted areas in yellow represent regions involved in ventilatory control. N=3; ND: not determined.
