2010). Other neuropeptides with established roles in linking stress and addiction-related behavior include dynorphin (Bruchas et al., 2010) and neuropeptide Y (NPY) (Heilig et al., 2010). More recently, however, additional neuropeptides including the urocortins (Ucn), neuropeptide S (NPS), nociceptin/orphanin FQ (N/OFQ) and neurokinins (NK), have been implicated in processes that link stress responses with drug seeking, drug taking, and long-term neuroadaptations. In this review, we focus on their involvement in alcohol-related behaviors, also considering their contribution to stimulant and opioid-related processes when data are available.
