High gamma threshold calls had 13.2 percent more adjacent pairs than fixed-count random orders in ten-second clips from eight SEEG records
We tested the time order of one-second high gamma calls in 30 ten-second clips from each of eight second-session SEEG records. Each person had 32 fixed contact pairs. Calls required power above each pair's early calibration 90th percentile. There were 2356 adjacent call pairs. Random orders with the same count in each pair and clip predicted 2081. The observed fraction was 3.409 percent. The reference fraction was 3.011 percent. The relative excess was 13.2 percent. The equal-person excess was 0.398 percentage points. Its descriptive 95 percent person interval was 0.235 to 0.545 points. Seven of eight people had a positive excess. All planned checks retained a positive mean. A constant-rate independence model gave a lower reference fraction of 1.807 percent. The study adds a tool for tests of successive-call rules. It reuses an existing cohort and has no command truth labels. It does not show a neural cause, intended commands, or safe stimulation. All 576 source ranges matched their hashes. All rebuilt arrays and a clean numerical replay matched. The package preserves code, inputs, calls, tables, four figures, provenance, and a source retrieval recipe.

We reused its feature arrays and retrieval code for eight people. We also reused raw witnesses, sample selections, source metadata, and range hashes. This study tests adjacent calls and runs after it holds each clip call count fixed. We rebuilt all features from the pinned public ranges.

Its time-clustering result on the same SEEG features supports concern about the exchangeability assumption in the rank bound. This test uses no analysis code from that result.

This study used its method for random orders with fixed local counts as context. No code or data were copied. The dataset and output endpoint differ.
