Fig. 4: Expression of dopamine receptors is modulated by the nutritional status but is not associated with cognitive impulsivity during refeeding in female mice.

A–C Expression of dopaminergic receptors DRD1 and DRD2. D Correlation matrix between kDD and the expression of dopaminergic receptors DRD1 and DRD2 in the PFC, DS, NAcc in the FR + R group. Data are expressed as mean ± sem and individual values. *p < 0.05, ***p < 0.001. CT control, DS dorsal striatum, FR food restricted, FR + R food restricted + refed, kDD devaluation coefficient, NAc nucleus accumbens, PFC prefrontal cortex.
