With 165 sounds per study, matching repeats gave higher spatial forecast scores in six SEEG patients and eight fMRI adults

We tested whether spatial response forecasts transfer across sound groups and whether test-repeat matching changes the score. A fixed first test used signed iEEG LFP means from 17 patients and BOLD fMRI from 16 adults. Mean gains were 24.139 and 12.281 training-energy points, but electrical pre-onset gain was also positive. This control motivated a follow-up with three repeat roles and 165 sounds per study. A third repeat fitted weights on other groups. The gains from matching repeats were 5.982 in six SEEG patients and 9.459 in eight NH2015 fMRI adults. Their 95% person Student limits were [2.924,9.040] and [6.844,12.074]. All matching differences were positive. The follow-up shared test passed two-test Holm correction, p=0.03125. The positive crossed-gain claim failed, p=1: every person had negative crossed-repeat skill. An exact loss identity expresses the matching advantage as alignment of target and forecast repeat changes. Common-sound refits retained positive advantage ranges. Reused MRI cohorts and the related controls make this a follow-up, not full independent confirmation. The separate clinical source adds a new test of this endpoint. Pre-onset SEEG advantage was also positive. All failures remain. Separate cohorts, source screens, clinical coverage, small samples, measurement filters and fixed sound panels limit scope. A common-input model gives the same advantage without links between readouts. The fixed follow-up did not show useful crossed-repeat forecasts. No latent neural noise source or common cause was established. The package gives code, permitted inputs, exact source records, all results, figures and repeat steps.
