Selected sites in eight SEEG patients showed mean beta recovery without a detected rise above baseline, assuming independent patients and symmetric null effects

This study tested late beta power at SEEG sites selected for response beta loss in eight people with epilepsy. The data came from OpenNeuro ds004473, version 1.0.2. Site selection used 986 trials. Tests used 986 separate trials and 87 selected bipolar pairs. The test mean response effect was -1.03 dB relative to baseline. Late power rose by 1.04 dB from the response window. Both exact patient tests had Holm p = 0.046875 under independent patients and symmetric null effects. Late power was +0.009 dB relative to baseline. Its 95% t interval was -0.335 to +0.353 dB and Holm p was 0.953125. The late window covered 0.7 to 1.5 seconds after the recorded response. The result supports recovery at the selected sites. It does not prove equal power or the absence of a rebound at other sites or times. The package contains input powers, split and site tables, source metadata, raw fixtures, code, figures, and reproduction instructions.
