Abstract:
Introduction: In the central nervous system, cocaine- and amphetamine-regulated transcript (CART) 55-102 peptide is localized in areas, such as the ventral tegmental area, amygdala, hypothalamus, and hippocampus, where emotional activity is regulated. Studies on the effects of the intracerebroventricular (ICV) administration of CART peptide on behavior remain limited. The findings from these studies suggest that this neuropeptide has anxiogenic-like effects. In the central nervous system, neuropeptide Y (NPY) has similar localization as CART. Previous behavioral studies have demonstrated that the ICV administration of NPY has anxiolytic-like effects.
