  • 1

    The study by Sugita et al. on motor learning after subarachnoid hemorrhage has been retracted due to serious inaccuracies.

  • 2

    Inaccuracies were found in reported age, WFNS grade, and GABA measurement values in the study's Table 1.

  • 3

    The MRI scanner used for data collection is no longer available, preventing correction of the outdated data.

  • 4

    The article's conclusions are no longer supported by the data, leading to its retraction.

  • 5

    The retraction was authorized by Frontiers’ Chief Executive Editor and the Neurological Biomarkers Chief Editor.
