A sign-flip test with a symmetric null did not detect increased hippocampal theta harmonic phase consistency during memory maintenance in 12 SEEG patients
We tested theta to second harmonic phase consistency in public hippocampal SEEG from 12 patients. We used 44 matched adjacent pairs, two task sessions, and 1,085 trials. The mean late memory maintenance minus fixation change was -0.00382. The 95% Student t interval was -0.01593 to 0.00829. The exact patient sign-flip p value was 0.52002. This test requires independent patients and symmetric null differences. It did not detect a rise and does not establish no change. The same coefficients reproduced the prior mean theta power rise of 1.25 dB. The package contains the fixed plan, phase estimates, source checks, code, and retrieval instructions.

We used its sample, complex Fourier coefficients, raw examples, metadata, source pins, and EDF code. We checked the used source ranges and added a harmonic phase analysis. The cohort is shared.
