WITHDRAWN: Phase-lag-dependent modulation of interhemispheric β-band functional connectivity by dual-site tACS

The manuscript was withdrawn because a code bug substantially affected the main analysis results, and the primary DKL metric handling for negative values was inappropriate.

• Why it matters: The work was intended to report phase-lag-dependent modulation of interhemispheric β-band functional connectivity by dual-site tACS, but methodological errors undermine the reported findings.
• What they did: The authors identified a major bug in the analysis code and noted that DKL is not defined for negative values, with an attempted transformation that did not appropriately address this issue.
• The result: Because these problems could materially change the conclusions, the authors ask that the work not be cited as a reference for the project.
