Fixed neural readers tracked pain reports across heat levels in 117 EEG and 20 fMRI adults; another MRI test failed
We fitted neural weights to pain report differences at one fixed heat level. We tested them at another level in other people. Separate public studies supplied scalp EEG and BOLD fMRI. Reference people selected penalties using both transfer directions. They then supplied each fit at one input level. A local code lock preceded tests in 117 EEG and 20 MRI adults. We controlled order and, in MRI, cues before within-level correlations. EEG mean correlations were 0.1683 from low to high input and 0.2169 in the reverse direction. MRI means were 0.1420 and 0.1595. All four 95% person Student limits were positive. The shared rule required Student and sign-flip evidence in all four cells. Its Holm p was 0.02272 across the final three claims. Person resampling gave positive central ranges. Both frozen EEG readers tracked reports in 107 eligible adults from another study. Added sparse MRI tests in 82 adults failed after heat and context control. Mean correlations were 0.0084 [-0.0520,0.0688] and 0.0423 [-0.0164,0.1011]. Stronger context checks in the first MRI study were also uncertain. We keep all failures and negative people. The evidence supports fixed transfer under stated controls. It does not confirm general MRI transport or full context invariance. It does not establish pain specificity, clinical calibration or causality. Whole-record features, personal scaling, source selection, different cohorts and measurement filters limit scope. The package gives permitted inputs, source versions and terms, code, weights, results, figures and repeat steps.
