AI Article Synopsis
- PVN hypothalamic norepinephrine (NE) injections promote feeding but reduce preference for sweet and starchy foods like saccharin and almond/lemon flavors.
- The injections also increase a negative reaction to bitter tastes, like quinine.
- These findings suggest that NE in the PVN helps stimulate eating by dampening feelings of fullness.
Article Abstract
Paraventricular (PVN) hypothalamic norepinephrine (NE) injections which facilitated feeding were nonetheless found to reduce both the unconditioned preference for saccharin and starch-conditioned preferences for almond odor and lemon taste, as well as enhancing aversion to quinine. These results add to the evidence that PVN NE elicits eating by attenuating a satiety signal.
