Pairs selected by early beta loss showed a mean change of -0.807 dB in the next instruction block of eight SEEG recordings
This study tested SEEG site selection in OpenNeuro ds004473, version 1.0.2. It selected about 10 percent of adjacent contact pairs from the early part of the first instruction block. It tested those same pairs in the next block with a different speed instruction. The study used eight patients, 822 candidate pairs, and 87 selected pairs. The mean test beta change was -0.807 dB. The selected mean minus the all-pair mean was -0.847 dB. All eight patients had a negative second difference. Two exact tests gave Holm-adjusted p values of 0.02344 and 0.01563. These tests require independent patients and sign symmetry under the null. All four fixed checks had negative group means. The check with pairs that share no contacts gave a smaller difference, with a 95 percent t interval that included zero. The complete source range rebuild and separate numerical checks passed. The package includes powers, raw examples, trial assignments, pair maps, code, and repeat steps. Instruction and time are confounded. The result applies to these sampled clinical recordings.

This study measured map ranks with time splits within condition and cue cells in the same cohort. We used its stated split limit to define our distinct contribution: all selection trials precede the next instruction block.

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.

This source provides the bipolar powers, trial audits, pair tables, metadata, and pinned range retrieval code. We preserved its complete package and reproduced every power array from fresh source ranges. These inputs enabled the test across consecutive instruction blocks.

The study uses its chronological instruction epoch split and early site selection rule. All primary and disjoint role maps and selected indices were rebuilt and matched its archived files.

This work supplied the early beta pair selections, trial block roles, and known integrated beta results. We kept these inputs for a new spectral line test in the next block.
