Statistical maps (Supplementary Figs 1,2)

Nifti files containing group statistical maps comparing alpha- and gamma-band power during 'attention left' and 'attention right' trials. 'Alpha_tmap' and 'Gamma_tmap' show whole-brain statistical maps. The other volumes are masked by cluster-based permutation test. Note - in order to view the t-maps correctly it is necessary to use a bidirectional colour map that can display positive and negative values using different colours, such as 'jet' or 'flow'.
