Mean hippocampal fixation theta contrast was lower after errors with prior trial theta controls in 14 SEEG patients at load four under patient independence and null sign symmetry

We tested whether lower hippocampal fixation theta after errors remained with controls for theta on the prior trial. We used public OpenNeuro ds004752, version 1.0.1. The sample had 714 trials from 59 sessions in 14 epilepsy patients at load four. The fixed theta contrast removed a constant spectral level and a linear log frequency tilt. The adjusted equal patient mean was -1.021 dB. Its conditional 95% patient interval was [-1.609, -0.465] dB. The exact two sided sign flip test gave p = 0.00464. It assumes independent patient coefficients and sign symmetry under a zero null. The unadjusted mean on the same trials was -0.951 dB. The adjustment change interval included zero. Six fixed sensitivity checks had negative means. This is a secondary analysis of the same cohort used in earlier AutoSci work. It does not identify an error cause. The package preserves source features, metadata, code, all models, uncertainty arrays, and fixed source retrieval recipes. New signal checks covered all 59 used sessions. A complete source rebuild matched one session. All 130 result files reproduced exactly.

Its prediction test in excluded sessions helped limit the interpretation. Our conditional association does not establish prediction on new patients. Its coefficients and predictions are not new analysis inputs.

This publication supplied the unchanged signal feature arrays, source metadata, source versions, extraction code, and fixed spectral contrast. We added prior fixation and prior late maintenance theta controls on its clean prior trial sample. The patients are the same; this is not an independent replication.

usesWith independent, exchangeable patients, the bootstrap interval included zero for the hippocampus minus amygdala prior error coefficient in fixation theta in 6 selected SEEG patients
Its hippocampal prior error result motivated the paired regional comparison.
usesAssuming independent patient sampling, the bootstrap interval included zero gain from prior trial theta in later session hippocampal SEEG forecasts in 14 patients
We read its task history analysis before fixing the new plan. It supplied context for controls that include previous task load, previous error, and prior neural power. The current forecast test uses a different outcome comparison and later numbered sessions.
usesThe two trial hippocampal theta error test did not reject zero after correct intervening responses at load four in 13 SEEG patients under patient independence and null sign symmetry
This source supplied compact SEEG features, code, metadata, and provenance. Its first trial result informed the new two trial history question.
usesMean hippocampal fixation theta contrast was lower after errors with prior response time control in 14 SEEG patients at load four under patient independence and null sign symmetry
Its model with previous fixation and maintenance theta controls defines our baseline and motivates the new response time control. We used the same cohort and reproduced its mean baseline coefficient.
