Title Alpha modulation source maps (Fig 2C)
Downloaded 7 times
Description Nifti file containing a map of the grand average alpha modulation index scores from all 26 subjects, normalised to MNI space, as shown in Fig 2C. Note - in order to view this file 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'.

Title Alpha modulation TFR - sensor level (Fig 2A/B)
Downloaded 5 times
Description Fieldtrip structure containing a time-frequency representation of the grand average alpha modulation index scores from all 26 subjects at the sensor level. The user will need to download and install the fieldtrip matlab toolbox (http://www.fieldtriptoolbox.org/) to visualise this data. The following matlab code will reproduce the bottom rows of Fig 2A and Fig 2B from this structure: figure cfg=[]; cfg.zlim=[-9 9]; cfg.channel={'MLO*'}; subplot(2,1,1),ft_singleplotTFR(cfg,amod_g); cfg.channel={'MRO*'}; subplot(2,1,2),ft_singleplotTFR(cfg,amod_g);

Title Statistical maps (Supplementary Figs 1,2)
Downloaded 10 times
Description 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'.
