| κ-Opioid Receptors | |||
| Ad libitum | VMH/ARC | 0.97±0.08 | |
| Deprived | VMH/ARC | 0.84±0.11 | 0.34 |
| Ad libitum | LH | 0.77±0.05 | |
| Deprived | LH | 0.73±0.05 | 0.61 |
| Ad libitum | PVN | 0.39±0.07 | |
| Deprived | PVN | 0.51±0.09 | 0.38 |
| δ-Opioid Receptors | |||
| Ad libitum | VMH/ARC | 0.82±0.07 | |
| Deprived | VMH/ARC | 1.38±0.31 | 0.09 |
| Ad libitum | LH | 0.93±0.08 | |
| Deprived | LH | 0.90±0.07 | 0.81 |
| Ad libitum | PVN | 0.32±0.06 | |
| Deprived | PVN | 0.37±0.06 | 0.55 |
Values are means ± SE. Gene expression of μ-, κ-, and δ-opioid receptors was not significantly different between the ad libitum and the food-deprived group.
