Multivoxel pattern analysis of WM data. The results of a multivoxel pattern analysis using the 60 most spatially selective voxels in each V1 ROI during a time period extending from 6 to 16 s after the offset of the sample stimulus. The horizontal line at 0.5 denotes chance classification accuracy. ROIs both contralateral and ipsilateral to the sample stimulus discriminated its orientation but only when active WM maintenance was required. Qualitatively similar results were obtained across a range of pattern sizes (50 and 75 voxels) (supplemental Fig. 2, available at www.jneurosci.org as supplemental material) and also when a linear discriminant algorithm was used to perform classification. Error bars represent ±1 SEM.
