A. Examples of raw traces from bilateral diaphragm EMG recordings during basal breathing before (Naïve) and throughout experimental time points post-injury (1 day, 1, 2, 4, 6 and 8 weeks post-C2Hx). EMG_I – ipsilateral EMG, EMG_C – contralateral EMG; B. Averaged amplitudes of integrated diaphragm activity (EMGs) as a percent of pre-injury level in 7 animals recorded before (b) and 1 day (1d), 1 week (1w) through 8 weeks (8w) post-C2Hx for ipsi- and contra- sides
