Position coding in spatial working memory
Figure 4. Differences in early and late phases of the delay activity between task conditions thought to promote either retrospective sensory or prospective motor coding, respectively.
Specifically, dense whole-brain results are presented for contrasts between A. match and non-match conditions, and B. center and off-center conditions in Experiment I, and C. center and off-center conditions in Experiment II. Early delay was defined as activity in the first half of the delay period, and late delay was defined as activity in the second half of the delay period. Differences between task conditions were calculated using permutation t-tests on dense whole-brain data, corrected with cluster (C = 3.1) FWE, and thresholded at p
