Correction: Emrich et al., Distributed Patterns of Activity in Sensory Cortex Reflect the Precision of Multiple Items Maintained in Visual Short-Term Memory
Introduction
In the article “Distributed Patterns of Activity in Sensory Cortex Reflect the Precision of Multiple Items Maintained in Visual Short-Term Memory” by Stephen M. Emrich, Adam C. Riggall, Joshua J. LaRocque, and Bradley R. Postle, which appeared on pages 6516–6523 of the April 10, 2013 issue, the following paragraph was omitted from the Materials and Methods section:
Data acquisition and preprocessing
Whole brain images were acquired with the 3T scanner (Discovery MR750; GE Healthcare) at the Lane Neuroimaging Laboratory at the University of Wisconsin–Madison. High-resolution T1-weighted images were acquired for all subjects with an FSPGR sequence (8.132 ms TR, 3.18 ms TE, 12° flip angle, 156 axial slices, 256 × 256 in-plane, 1.0 mm isotropic). BOLD-sensitive data were acquired using a gradient-echo, echoplanar sequence (2 s TR, 25 ms TE) within a 64 × 64 matrix (39 sagittal slices, 3.5 mm isotropic). Six runs, each lasting 13 min (390 volumes), were obtained for each subject. The first three TRs from each run were removed before analysis to achieve a steady state of tissue magnetization.
