Fig. 2. Time course of the effects of intracerebroventricular injection of (1) 0.5
µl vehicle (open bars, N=16), (2) 25 pmol NP
(horizontal-hatched bars, N=8), (3) 50 pmol NP
(cross-hatched
bars, N=9) and (4) 100 pmol NP
(gray bars, N=8) on
(A) fV, (B) VAMP, (C)
VTOT, (D) mean PDA, and (E)
fH in unanesthetized trout. The arrow indicates when the
injection was given. *P<0.05 vs vehicle at
corresponding post-injection period and vs pre-injection value.
