Specific Contributions of Ventromedial, Anterior Cingulate, and Lateral Prefrontal Cortex for Attentional Selection and Stimulus Valuation

Topography of the effects of spatial attention and target value during the attention shift.

(A) Mutual information between significant (p≤0.05) main effects of spatial attention (attend contra- versus ipsilateral stimulus) and location, as a function of the time relative to attention cue onset. The grey shading denotes time epochs with significant spatial clustering. (B) Fronto-cingulate map showing the distribution of the proportion of neurons with a significant spatial attention effect at 0.5±0.15 s after attention cue onset. The spatial areas with a larger proportion of significant neurons than expected by probability are highlighted by the black contours in the small map on the bottom right (see Materials and Methods for details). Each spatial map is overlaid by black contours, demarcating the area boundaries for the fronto-cingulate subdivisions as shown in Figures 1C and 2E. Area labels for each subdivision are indicated by the small inlet on the top-right of the figure. (C–D) Same format as (A,B), but now showing the mutual information between significant effects for target value (attention to target with high versus low expected outcome) and location.
