Fig. 4. Patient choice (less impulsive) and correlated activation to CS+.

(a) Activation map showing the region of correlation between preference for delayed money (ln k: $20) and activation to CS+ (relative to CS−) in right parietal cortex (BA 40) within the frontoparietal network, n=46. The main effect of [CS+ > CS−] BOLD activation in BA 40 is shown in green outline; displayed at puncorr < 0.01, extent = 200. (b) The nature of the correlation is illustrated by mean extracted values from the functional cluster in (a), indicating that greater BA 40 activation during CS+ presentation corresponds to less impulsive decision making.
