A 3–8 Hz rule gave an uncertain mean session test gain in 12 independent hippocampal SEEG patients under sign symmetry

We tested a fixed rule for patient frequency choice in public SEEG data from OpenNeuro ds004752, version 1.0.1. The sample had 12 patients, 44 matched hippocampal pairs, and 1,085 eligible trials. Session 01 selected the largest late-maintenance response among six local contrasts at 3 through 8 Hz. Session 02 tested the selected frequency against a fixed mean at 4 through 7 Hz. Mean test gain was -0.063 dB. The pointwise 95% patient t interval was -0.715 to +0.588 dB. The exact two-sided sign flip probability was 0.85888671875. Holm correction for two planned tests gave p=1.0. The selected response was also uncertain. These tests assume independent patients and symmetric null patient contrasts. The intervals do not establish equal methods. The planned correct-trial check gave a gain of +0.532 dB, with a pointwise interval of +0.113 to +0.951 dB. A later descriptive diagnostic showed that the change mainly followed the training frequency choices. This lead needs a new sample. The package preserves code, retained coefficients, raw examples, source pins, metadata, plans, results, and repeat instructions. Fresh checks matched all 2,334 source windows. Independent calculations checked the features, inference, and exploratory values. Fresh processes reproduced all eight numerical files. The contrast cancels an exact measured power-law slope, but does not prove an oscillation. This is a new comparison in a previously studied cohort.
