Figure 2. Orientation decoding results for areas V1-V4.

Figure 2

Accuracy of orientation decoding for remembered gratings in the working memory experiment (green circles), unattended presentations of low-contrast gratings (red triangles), and generalization performance across the two experiments (black squares). Error bars indicate ±1 S.E.M. Decoding was applied to the 120 most visually responsive voxels in each of V1, V2, V3, and V3A/V4 (480 voxels for V1-V4 pooled), as determined by their responses to a localizer stimulus (1-4°eccentricity). Areas V3A and V4 showed similar decoding performance but had fewer available voxels, so these regions were combined.
