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

The relationship between firing rate and the association of the cued target's color and liquid volume.

(A) Fronto-cingulate distribution of neurons with a significantly (p≤0.05) higher firing rate for the high-value than for the low-value condition. The small map on the bottom right shows the cluster with a statistically significant spatial concentration of neurons whose firing rates were elevated when the color of the cued target was associated with a high-value reward. (B) Normalized firing rate as a function of time, separately for the high (red, solid line) and low-value (blue, solid line) conditions, averaged across the 18 neurons recorded within the contour that is shown in the small map in (A), spanning anterior cingulate area 24 and ventromedial area 32. (C) Same format as (A), but showing the spatial distribution of neurons with a higher firing rate for the low-value than for the high-value condition. (D) Same format as (B), but showing the normalized firing rate averaged across the 26 neurons that were recorded within the contour shown in the small map in (C), spanning parts of areas 32 and anterior area 24.
