Correlations between selectivity index and value effects on BOLD signal in 3 ROIs from Kirchhoff and Buckner (2006):
(A) Anterior L IFG (BA 45/47)
(B) Posterior L IFG (BA 44/6)
(C) Extrastriate visual cortex (BA 19/37)
Regions A and B, which have been associated with verbal strategy use, show significant correlations between selectivity index and value effects on BOLD signal. Region C, a visual association area that has been associated with non-verbal encoding strategies (BA 19/37), does not show a significant correlation.
