Figure 6. Model-free neural evidence of value contextualization.

Figure 6

(a) Bars represent the regression coefficients extracted in the ventromedial prefrontal cortex, as a function of the task contexts (represented by different colours) and leaning phase (early: first eight trials; late: last eight trials). Regression coefficients are extracted from the model-free GLM2 within a sphere centered on literature-based coordinates of the ventromedial prefrontal cortex11. (b) & (c) Bars represent the regression coefficients for best>worst outcome contrast as a function of the task contexts. (‘+0.5€>0.0€': best>worst outcome contrast in the reward contexts; ‘0.0€>−0.5€': best>worst outcome contrast in the punishment contexts). Regression coefficients are extracted from the model-free GLM3 within spheres centered on literature-based coordinates of the striatum and anterior insula8. Y coordinates are given in the MNI space. Note that ROI selection avoids double dipping, since the ROIs were defined from independent studies (metanalyses). *P<0.05 one sample t-test comparing between regressors (black ‘*') or to zero (white ‘*'; N=28); NS: not significant. Error bars represent s.e.m.
