Here is one recent review article with further references:

They have a nice summary picture.<p>The first paper that this press release talks about is about amygdala contribution to this process (at least for cocaine addition), where the basolateral amygdala (BLA) is involved as neural involvement in behavior shifts from the ventral to anterior dorsolateral striatum (DLS) and then the amygdala contribution changes to the central nucleus.<p>It looks like the BLA pathway to the anterior DLS they describe is through the core of the nucleus accumbens to the substantia nigra.  The central amygdala projects directly to the substantia nigra.<p>I found this paper exploring the connection of the central nucleus and the DLS (&quot;Amygdala central nucleus interacts with dorsolateral striatum to regulate the acquisition of habits&quot; by Lingawe and Balleine):
