Figure 6. Neural food reward processing is related to hormonal satiety parameters and lifetime maximal weight.
(A) Percentage signal change of BOLD activation extracted from the right ventral striatum during the expectation of food-related reward (high reward: 10 snack points) when satiated was positively related to ghrelin total values (Pearson r(11) = 0.611, P = 0.027, 2-tailed correlation, n = 13). (B) Percentage signal change of BOLD activation extracted from the left ventral striatum during the expectation of a food-related reward (high reward: 10 snack points) during the fasted state was negatively related to lifetime maximal weight (r(21) = –0.433, P = 0.039, 2-tailed correlation, n = 23).
