Late-to-pre beta change maps had positive early and late trial agreement in seven of eight SEEG recordings
We tested spatial beta power change across early and late task trials in eight public SEEG recordings. The data came from OpenNeuro ds004473, version 1.0.2. We compared 0.7–1.5 seconds after the key response with 0.8 seconds before it. We removed each map’s spatial mean and measured the product of the early and late maps. Seven of eight patient estimates were positive. The patient mean was 0.2645 dB², with a patient bootstrap interval of 0.0792–0.4648 dB². Interpretation as mean-map agreement requires zero mean errors and no error covariance between halves. One patient had negative agreement despite a positive pooled squared map size. We preserve 822 pairs, 1,860 trials, source provenance, maps, code, raw checks, and exact reproduction records. This reused cohort does not identify a neural cause.

Its response-to-baseline rank-map time split study helped choose the task-cell time split. This work tests late-to-pre power change and a centered map product in the same cohort.

Its source event and behavior audit reported correctness-field conflicts. This finding helped set the rule to use recorded response keys without selection by the correctness field.

This study used the fixed source metadata, raw retrieval code, range hashes, and trial and pair rules. Fresh raw downloads reproduced all archived beta powers exactly. The new calculation added gamma powers.
- usesFixed high gamma and beta models gave 48.1 and 48.5 percent balanced accuracy for response keys on later trials in eight SEEG recordings
This work supplied the EDF reader, fixed trial and contact pair selection, metadata, and pinned byte range hashes. We retrieved the same raw ranges and added high gamma power features.
