these results show that the phasic responsiveness of nac da transmission to an unfamiliar palatable food is under strong modulatory control by primary (consummatory) and secondary (appetitive) stimuli, and that the sign and extent of this control depends on the nature of the appetitive stimulus, delay of reward and motivational state (deprivation). |

T H Park, K D Car. Neuroanatomical patterns of fos-like immunoreactivity induced by a palatable meal and meal-paired environment in saline- and naltrexone-treated rats. Brain research. vol 805. issue 1-2. 1998-11-25. PMID:9733960. |
since naltrexone, alone, increased fli in vta, nac shell, central amygdala (cea) and laterodorsal bed nucleus of the stria terminalis (bstld), the blunting of ingestion reward by naltrexone may result from direct or transsynaptic activating effects on opponent neuronal activity within this highly interconnected set of structures that mediate and modulate reward. |

A Her. Endogenous opioid systems and alcohol addiction. Psychopharmacology. vol 129. issue 2. 1997-06-16. PMID:9040115. |
one hypothetical model proposes that reward results from activation of mu-opioid receptors in the vta and/or delta-receptor in the nac; both these nuclei are targets of endogenous beta-endorphin. |
