Fig. 4: Task-related and choice history signals across cortical areas.
From: Persistent activity in human parietal cortex mediates perceptual choice repetition bias
Effect sizes from a general linear mixed model (see “Methods”) estimating impact of stimulus category (a), choice (b–d), and action (e–h) on MEG power, in different regions and frequency bands. a Effect of current stimulus category on gamma (top) and alpha (bottom) power during test stimulus (n = 60). b As a, but for effect of previous choice in the reference interval. c As b, but for test stimulus interval. d Comparison of choice history signals between alternators (n = 25; orange) and repeaters (n = 34; purple). Group effect = 0.55328, CI [0.19342, 0.91314], p = 0.00258. e Effect of current action preparation on gamma (top) and beta (bottom) power during test stimulus (n = 60). f As e, but for effect of previous action during reference interval. g As f, but for the test interval. h Comparison of action history signals between alternators (n = 25; orange) and repeaters (n = 34; purple). Data are shown as average fixed effect size +/− 95% confidence intervals; *0.01 < p < 0.05 (no such effect present); **0.001 < p < 0.01; ***p < 0.001; filled markers, p < 0.05 (all p values FDR corrected).
