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

Latency and temporal evolution of spatial attention effects.

(A) Fronto-cingulate distribution of latencies of the spatial attention effects. Latency was measured separately for every pixel of the map that had a minimum of five neurons with a significant effect, as the first time after the attention cue onset where for two consecutive time windows the proportion of neurons with a significant spatial attention effect exceeded 3 SD of the proportion of significant effects in the pre-cue period (see text and Figure S5 for details). The panel on the bottom right shows the histogram of latencies across all pixels of the map. (B) Temporal evolution of the proportion of significant spatial attention effects for two pixels in area 46 (cyan line) and anterior area 24 (magenta line) as indicated by colored squares on the contour map to the left. The cross-hairs highlight the identified latencies. (C) Same format as in (B), showing the temporal evolution of significant spatial attention effects for the three pixels from area 32 (magenta), posterior area 24 (cyan), and area 9 (orange). (D) Fronto-cingulate maps of the proportion of significant spatial attention effects from −0.2 to 1.2 s following attention cue onset.
