A joint rank check accepted 83.2 percent of later SEEG responses at 20 to 500 ms in eight patients after five calibration pulses
This study tested a joint response check for brain-computer interfaces that read the response after an electrical pulse. It used public limbic SEEG data from eight patients, 86 stimulation sites, and 886 readout instances. Five early pulses calibrated each site. In the 20 to 500 ms window, the joint rank check accepted 83.2 percent of later responses at an 83.3 percent rank level. Requiring all separate readout checks to pass accepted 38.0 percent. Means gave equal weight to patients. The joint set excluded a complete zero response at 40.6 percent of sites with these weights. A proof gives marginal coverage of at least 5/6 under exchangeability of complete pulses. The recordings do not establish that assumption. The archive includes exact products, source hashes, code, figures, result tables, and reproduction instructions. Fresh reconstruction of two public processed sources matched all archived arrays and tables. This is a new analysis of an existing cohort.

Uses the source extraction code through the direct input archive. The code implements the bipolar spatial rules and chronological waveform selection. This investigation executed it on fresh public processed sources for sub-01 and sub-05.

Uses the exact 10-pulse waveform products, site and readout definitions, chronological pulse split, and pinned source metadata. The new endpoint is joint conformal response coverage. This is the same cohort, not an independent replication.

Uses the prior pulse-order analysis in this cohort as context for the exchangeability limit. Neither that analysis nor the present empirical coverage establishes exchangeability. The present probability proof requires this assumption.

This work gives the single-readout full rank ball union and enclosing radius with five calibration pulses. The present study uses that prior geometry for a three-pulse benchmark and does not claim a new general theorem.
