Figure 3. Conjunction of neural representations of attribute values.

Multivariate response patterns in the VMPFC encoded trial-wise values of all choice-relevant food attributes (Tastiness, Healthiness) and altruistic attributes ($Self, $Other, Fairness) across regulation conditions, as indicated by a conjunction of attribute-specific decoding maps thresholded at p < 0.05, FWE corrected at cluster-level.

Figure 3—figure supplement 1. Conjunction of brain areas that encoded trial-by-trial values of all attributes.

Attribute values for Healthiness, Tastiness, $Self, $Other, Fairness. Each attribute was thresholded at p < 0.001, cluster-level corrected, k = 10 voxels. Not displayed are clusters in the supplemental motor area ([MNI −3 26, 46], 43 voxels) and visual cortex ([MNI −28,–85, 32], 15 voxels, [MNI −21,–67, 40], 10 voxels). Coordinates refer to center of mass for the identified clusters in MNI space (Montreal Neurological Institute), R = right hemisphere.

Figure 3—figure supplement 2. Exploratory functional connectivity analyses.

(A) Region of the VMPFC (red) where increased connectivity with the DLPFC during Health vs. Natural and Taste focus conditions correlates with Δw Healthiness in Health vs. Natural and Taste Focus. The yellow region shows the VMPFC ROI defined by the conjunction of all attributes. Orange indicates overlap. Inset: DLPFC seed region. (B) Region of the VMPFC (red) where decreased connectivity with the DLPFC during Partner and Ethics conditions compared to Natural predicted decreases in Δw $Self in Partner and Ethics vs. Natural condition. The yellow region shows the VMPFC ROI defined by the conjunction of all attributes. Inset: DLPFC seed region. (C) Region of the Precuneus where increased connectivity with the VMPFC during Partner vs. Ethics conditions Δw $Other weight in Partner vs. Ethics trials. Yellow region shows the VMPFC ROI defined by the conjunction of all attributes. Inset: Precuneus seed region. All results are shown thresholded at p < 0.005 uncorrected.
