This article was originally published with errors in figures 4 and 5. Specifically, in figure 4b, the horizontal axis labels “P2” and “P3” were incorrectly presented as “N2” and “N3”, and in figure 5b, the horizontal axis label “N1 S2” was incorrectly presented as “N1 S1”. The corrected figures are shown below. These have also been corrected in the article itself. We apologise for this error.
FIGURE 4.

a) Group mean of the respiratory-related evoked potential (RREP) of the first (S1) occlusion of the pairs in the frontocentral region, b) mean±sem of each RREP component with its related scalp topographies. *: p<0.05.
FIGURE 5.

a) Group mean of the respiratory-related evoked potential (RREP) for the first (S1) and second (S2) occlusion of the pairs in the centrolateral region, b) mean±sem of N1 S1, N1 S2 and S2/S1 ratio with their related scalp topographies.
