With fixed response filters, word gap tests did not confirm a shared increase in six iEEG patients and 28 fMRI adults

We tested whether longer annotated gaps before words predict larger auditory responses. Separate public studies supplied iEEG high-gamma amplitude and BOLD fMRI. One test used a log gap term above 200 ms. A second used a pause-onset coefficient. Both controlled word identity, sound, duration and next gaps. Development used three patients and six MRI adults. A local lock preceded tests in six other patients and 28 other MRI adults. The same MRI adults heard two stories. Mean prior grade scores were +0.01165, -0.00593 and -0.01708. All 95% person Student intervals crossed zero. Both fixed shared tests failed, with Holm p=1. Positive sound-response checks did not repair the failed tests. All negative people and failed sensitivity fits remain. In the MRI designs, very little prior grade variation remained after controls. Constant per-word response examples gave nonzero gap scores when the true response filter differed from the fit filter. They are model examples, not fitted human causes. We provide 10,062 numerical gap records, unchanged permitted compact neural inputs, code, source pins and terms, all results, figures and repeat steps. A shared neural recovery effect, a sharp biological threshold and causality were not established. Sparse clinical sampling, distinct cohorts and stories, source screens, broad MRI regions, timing errors and fixed measurement filters limit scope.
