Looking for Greener Pastures Humans, like other animals, have evolved to forage. Brain-imaging studies by Kolling et al. (p. 95 ) suggest that activity in the dorsal anterior cingulate cortex supplies a continuous signal of environmental richness predicted foraging theory. The exhibits frame reference is tied key decision whether engage with current choice or search alternatives. same strategy used when humans are making types decisions. In contrast, ventromedial prefrontal cortex, brain region lacks any signals pertinent foraging, encodes values manner uninfluenced richness.
