Figure 5

Illustration of how informative voxels may be missed in a single-subject searchlight analysis when information is not detected with equal power in all spatial frequencies. The yellow areas represent informative voxels while the red circles represent the searchlight. Assume all cluster voxels are required for significant classification. a. The cluster will not be detected because the searchlight is too small. b. The cluster will be not detected because the searchlight shape does not match the cluster shape. c. The cluster appears smaller in the information map since only searchlights containing the entire cluster are significant.
