Fig. 6. Mean discharge patterns of Early-I PhMNs.
The discharge onset time (A), spikes per neural breath (B), discharge duration (C) and discharge frequency (D) were quantified in control, 2 wk, 4 wk and 8 wk post-C2Hx animals at 50 mmHg PETCO2. * P < 0.05; **: P < 0.01 significant difference vs. control.
