Figure 6

Peak amplitude of crossed phrenic activity in P2, P7, P14, P21 and P28 groups. A) Peak amplitude of crossed phrenic activity in hemisection groups * represents significant difference between P2 and all the other postnatal groups respectively, # represents a significant difference between P7 and all the older age groups except P14, $ represents a significant difference between P14 and P21 as well as P28. Note the progressive decrease in the mean peak amplitude as the animals get older. B) No significant difference in peak amplitude among the non-hemisected groups.
