Brain activation in the ventral striatum during the expectation of a food or monetary reward. (A) Bar chart depicting percent signal change from the left ventral striatum (VS) during different anticipation conditions for the FID task. Error bars depict standard error of the mean. (B) ROI-masks were used to extract percent signal change for the FID task (left VS, depicted in blue) and MID task (right VS, depicted in red), rendered on a T1-weighted template image (coronal slice, y coordinate = 5 mm) supplied with micron (Colin brain). (C) Bar chart depicting percent signal change from the right VS during different anticipation conditions for the MID task. Error bars depict standard error of the mean.
