Fig. 5. Time course of the effects of intracerebroventricular injection of (1) 0.5
µl of vehicle (open bars, N=16), (2) 50 pmol NKA (cross-hatched
bars, N=7), (3) 100 pmol NKA (gray bars, N=8), and (4) 250
pmol NKA (filled bars, N=7) 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.
