Abstract
Amylin (50 μg/kg i.p.) did not change phasic DA responses compared to saline control rats. However, sCT (50 μg/kg i.p.) decreased evoked DA release to VTA-stimulation over 1 h compared to saline treated control rats. Further investigations determined that AP and bilateral PBN lesions abolished the ability of sCT to suppress evoked phasic DA responses to VTA-stimulation. These findings implicate the AP and the PBN as important sites for peripheral sCT to decrease evoked DA release in the NAc and suggest that these nuclei may influence hedonic and motivational processes to modulate food intake.
