Fig. 2: Regional HFB information accumulation and filtering effects supporting successful WM.

a Successful CL performance was linked to increased HFB activity to the second over first item (F(1,255) = 13.082, p = 0.0004). Data are represented as individual electrode datapoints, and condition probability densities and medians calculated across electrodes from all subjects (n = 145 electrodes from 11 biologically independent samples). Boxplots present the medians and interquartile ranges, and whiskers the 1.5 × IQR from the quartile. Source data are provided as a Source Data file. *p < 0.05. b Electrodes contributing to the significant correct > error effect in (a), overlaid on the MNI-152 template brain. Electrode size indicates the relative size of the item 2 > 1 difference on correct trials (0 < z < 6.75), consistent with information accumulation in WM. This figure was created using BrainNet Viewer⁷². c On correct CF trials, faster behavioral RT was linked to increased HFB activity to targets over distractors (F(1,276) = 6.86, p = 0.009; n = 145 electrodes from 11 biologically independent samples), same conventions as a. d Electrodes contributing to the significant RT correlation effect in c overlaid on the MNI-152 template brain. Electrode size indicates the relative size of the normalized RT × (target > distractor) correlation (−3.16 < z < 0), consistent with an open gate. This figure was created using BrainNet Viewer⁷².
