Past event length did not pass a shared hippocampal test across two films in 18 patients with spikes and 15 fMRI adults
We tested whether hippocampal responses at film boundaries increase with the length of the event that ended. The past-length slope also had to exceed the future-length slope. Separate human studies supplied intracranial spikes and fMRI. Seven spike patients supplied development. Fixed confirmation retained 18 other patients and 15 fMRI adults. The mean standardized direction slope was -0.113 in spikes and +0.099 in BOLD. The 95 percent person intervals were -0.243 to +0.035 and +0.043 to +0.160. Intervals that also varied common movie blocks were -0.319 to +0.097 and -0.030 to +0.248. The fixed shared rule failed; its joint one-sided person sign p was 0.984558. All negative scores and fixed checks remain. The positive fMRI direction result depended on the uncertainty model. This does not establish a causal modality difference, absent duration coding, or cross-modal generalization. Clinical sampling, distinct event labels, different response windows, source processing, and two fixed films limit scope. The package gives a compact numerical benchmark, code, plans, source hashes and terms, results, figures, and repeat instructions. A selected HDF5 download matched complete-file features exactly in an input audit.
