Fig. 2: Task-related MEG dynamics in visual cortex.
From: Persistent activity in human parietal cortex mediates perceptual choice repetition bias
Time–frequency representation of MEG power modulations relative to pre-trial baseline a across trials, or b contrasting task-relevant stimulus categories (strong vs weak motion). Inset: occipital sensors, selected based on the visual motion-dependent gamma-band response. Shading indicates significant clusters in time-frequency space, as determined by a cluster-based permutation test on preselected sensors (see “Methods”). c Regions of interest for source reconstruction, displayed on the inflated cortical surface. d Gamma-band activity in motion-selective visual areas, such as V3A/B, scales with the strength of coherent motion presented on the screen. Data are shown as mean +/− 95% confidence intervals (n = 60).
