Fig. 4. Time course of the effects of intracerebroventricular injection of (1) 0.5
µl vehicle (open bars, N=16), (2) 50 pmol SP (cross-hatched bars,
N=8), (3) 100 pmol SP (gray bars, N=10) and (4) 250 pmol SP
(filled bars, N=10) 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.
