A planned match rule retained 63 of 250 bilateral hippocampal SEEG records for a theta coupling test
A planned theta coupling test used 250 public bilateral hippocampal depth records from seven people. A one-standard-deviation limit on three pre-window features retained 63 records. The equally weighted person mean of actual change minus earlier matched control change was -0.01471 coherence units. The 95% person bootstrap interval was [-0.02805, +0.00173]. The exact two-sided sign-flip p value was 0.140625 under independent symmetric person contrasts. The test did not establish a decrease. An added audit held 41 records and their controls fixed. Its sample mean was negative with a five-second wait and positive with a ten-second wait. Both intervals included zero. The package preserves 250 source EDF files, pinned hashes, metadata, and a local pre-analysis plan. It includes code, validation, full results, and three figures. Earlier controls were not randomized sham periods. This study audits control support and measurement time for a possible BCI response measure. It does not establish a causal stimulation effect or clinical benefit.

This study adapts the retrieval code and earlier matched-control design. It reuses 189 raw records and the same seven source people. It adds a theta coupling endpoint, a coupling match feature, broader metadata selection, and timing audits.
