Fig. 4. Total power (WT) (A), steady power
(WS) (B) and oscillatory power (WO)
(C) in HH21 (WT: P<0.01;
WS: P<0.01; WO:
P<0.01) HH24 (WT: P=0.02;
WS: P=0.02; WO:
P=0.03) and HH27 (WT: P=0.40;
WS: P=0.41; WO:
P=0.42) control and experimental groups. All power parameters
significantly declined post-ligation in LAL groups, reflecting a decrease in
preload. However, by HH24, power parameters became more similar to CON values
and normalized by HH27. Power parameters also decreased in VAL embryos after
ligation and normalized by HH27. Symbols and abbreviations described in
