A whole-brain ANCOVA using the test phase difference score as a
covariate identified bilateral posterior cingulate regions in which the
BEFORE to AFTER changes in valence sensitivity correlated with the
changes in test phase performance from BEFORE to AFTER the manipulation
(Fig. 8). In PCC, increases in valence sensitivity correlated with increases
in test phase performance, suggesting that heightened feedback
responses in PCC may contribute to learning. Additional regions, which
instead demonstrated an inverse correlation between the changes in
test phase performance and the changing valence sensitivity, are included
in Table 3.
