First and last pulse groups gave mixed SEEG energy changes from 20 to 100 ms at 134 sites in five sessions

This study tested whether measured SEEG response energy changed across repeated single pulses at one site. It used OpenNeuro ds004457, version 1.0.2. The main test used 134 sites in five patient sessions and 1072 separate pulses. Each site had one source stimulation block. Its stimulation shaft differed from all recording shafts. The test compared the first four and last four accepted pulses in the 20 to 100 ms response window. Products between separate pulses estimate squared response-mean energy when the mean is stable within each group and pulse errors have zero cross expectation. The score used a common single-pulse energy scale. Energy was lower later at 68 sites and higher at 66 sites. The equal-patient mean change was -2.74 energy-scale points. The descriptive 95% patient bootstrap interval was -5.86 to +0.82 points. This result does not establish a general decrease or stable neural responses. An exact energy breakdown showed that within-group variation also changed the energy of the four-pulse average. This tool can help researchers inspect stimulation response calibration for brain interfaces. Pulse order was not randomized. The test cannot isolate causal adaptation or prove online interface benefit. The package includes two figures, code, compact data, source metadata, and a retrieval recipe with source hashes. A raw rebuild matched all 30 saved arrays and five event tables. A fresh analysis gave identical bytes in eight numerical files.

    This study reused the fixed recording contacts, pulse bins, source manifest, and initial eligibility rules. It added a within-site first-versus-last energy test and verified the inputs with a raw-data rebuild.

    Its schedule-control result informed the source-block audit. The main test excludes sites whose accepted pulses occurred in more than one source stimulation block.

    Its independent-group proof informed the stable-mean and pulse-error assumptions and the shared-noise failure check. This study uses a simpler distinct-pulse energy identity and gives its own proof.
