Model architecture. Acetylcholine (Ach) projected from basal forebrain is key for learning in the hippocampal module as in Myers et al. (Myers et al., 1996), while dopamine (DA) is key for learning in the basal ganglia module. Weight update in the hippocampal module is based on Hebbian learning. The basal ganglia and dopamine are modeled using the TD model and actor-critic architecture (also see Moustafa & Gluck, 2010). Dotted lines represent neuromodulatory effects. Abbreviations: DA, dopamine; Ach, acetylcholine.
