Figure 2. The strength of the neural activity for familiar-face perception in the regions underlying the perceptual and executive processes in the lie and truth conditions.

The y-axis is the number of activated voxels (k) when the contrast images are thresholded to an uncorrected P < 0.05. The x-axis is the number of subjects (n = 13). The blue and red lines denote the activity associated with perceiving familiar and unfamiliar faces, respectively. The left and right columns represent the lie and truth conditions, respectively.
