Figure 6. Contrast and attentional modulation in the LGN and SC.

Figure 6

A, B. The average attentional modulation index (AMI) across the two stimulus types is plotted against the contrast modulation index (CMI) for all voxels, pooled across subjects. Each dot represents a single voxel in the LGN (A) or SC (B). C. The mean AMI for each CMI is computed for the LGN (lower curve) and SC (upper curve) by smoothing the scatter plots in A and B with a Gaussian window (σ = 0.1). The shaded area represents the SEM.
