The 95 percent patient resample interval included zero for encoding contrast prediction gain under a fixed model in six SEEG patients
We tested frontal and temporal encoding power contrasts for recall prediction in public SEEG data. The main group had six Utah patients and 1,159 complete trials from OpenNeuro ds006136, version 1.0.1. A fixed ridge model added beta and high gamma contrasts to ten control features. Mean error reduction was 0.002638 objects squared, or 0.494 percent of baseline mean error. The 95 percent patient resample interval was -0.003669 to 0.009064 objects squared. Three patients had lower error. The exact sign flip test gave p = 0.50 under independent patients and symmetric gains under a zero null. The training-mean predictor had lower mean error than both main models. Fixed checks gave different gain directions. The package keeps joined data, source pins, code, predictions, and independent checks. All source features were rebuilt with exact byte agreement. The result applies to this release and these models.

This earlier result tested frontal and temporal encoding contrasts. We used it to define a distinct question about contrasts across encoding time windows. We did not reuse its regional features or model scores.
