Fig. 4Ventral striatal time courses after feedback following search forages(A). Effect of search costs when search is chosen(B). Individual peak BOLD β weights for new encounter value (C, top) and peak BOLD β weights for new search costs on searching (C, bottom) 5 to 10 s after event onset both correlated with the proportion of forages on which participants searched. Increased coupling with left ventral striatum as a function of search cost during searches (D) and individual differences in foraging readiness E) both revealed an ACC region anterior to, but overlapping with, that in Fig. 2D.
