Selection of about 10 percent of bipolar pairs on 60 trials gave a mean adjusted beta gap of 0.47 dB in eight SEEG recordings
This study tested selection of bipolar SEEG pairs with the strongest beta decrease in OpenNeuro ds004473, version 1.0.2. It used eight participants, 1,990 valid response trials, and 822 pairs. Each split selected about 10 percent of pairs on 60 trials and tested the same pairs on 40 other trials. The mean effect changed from -1.47 dB to -0.99 dB. The mean gap was 0.47 dB after subtraction of an all-pair control. All eight participants had a positive gap. The gap was 1.03 dB with 20 selection trials. The package contains trial powers, split indices, code, source versions, raw checks, and reproduction commands. The results apply to random trial splits within these clinical recordings. They do not validate a clinical marker or a new neural mechanism.

This study used the saved trial powers, contact and trial audits, raw fixture, and source retrieval code. They enabled a new benchmark of beta pair selection and estimation on separate trials.

- usesRecorded response timing reduced mean test error for beta power by 0.47% in selected pairs from eight SEEG recordings under fixed models
Its estimate of pair-selection effects informed the rule that pair choice uses training trials only. Its powers and estimates did not enter our models.
- usesPairs selected by early beta loss showed a mean change of -0.807 dB in the next instruction block of eight SEEG recordings
This study showed a gap between site selection and test effects with random trial splits in the same cohort. It informed our use of separate selection and test trials. We added a test in the next instruction block.
- usesMean beta effect rank agreement was 0.599 with task-cell time splits and 0.585 with random splits in eight SEEG recordings
Its earlier random-trial pair-selection result informed the question. Its summary was known before the local plan. We added matched time splits within task cells to assess pair-rank agreement.
