Fig. 3. (A) Frequency of breathing pauses and (B) proportion of total breathing
occupied by apnea in s min1 in zebrafish during normoxia
(black bars; N=4 pausers out of 10 fish) and during hyperoxia (white
bars; N=8 pausers out of 10 fish). (C,D) Representative original data
recordings from normoxic (C) and hyperoxic fish (D).
Statistically significant difference (P<0.05)
between the two groups.
