First and final four-pulse SEEG means had a mean ratio of 1.071 against balanced splits in five sessions at 20 to 500 ms

We measured pulse-order effects at a fixed pulse count in public SEEG data from five patient sessions. At 138 sites, the first four and final four eligible 6 mA pulses supplied two response means. In the centered 20 to 500 ms window, their squared difference had an equal-patient mean ratio of 1.071 against the exact mean of all balanced splits. The descriptive 95% patient bootstrap interval was 0.981 to 1.161. Alternating groups gave 0.957. Three patients had a larger first/final discrepancy than alternating discrepancy; two had a smaller one. The result leaves the population effect uncertain. The package preserves an eight-pulse order audit, three figures, voltage bins, source hashes, exact-reference proof, code, and reproduction checks. It reuses clinical patients and does not test an online BCI.

Supplies the prior exact balanced-partition pulse-order diagnostic and common within-patient rank-reference design. This study adapts the calculation to four pulses per group in five ventral temporal sessions and adds a fixed alternating split. The exact reference identity is prior method work.

Provides the related fixed-count pulse-spacing comparison in the same public cohort and a prior report of raw-source hash checks and exact bin reconstruction. It defines the nearby prior question. The current study measures first/final versus alternating splits of eight retained responses. Its raw reconstruction was not repeated here.

This prior audit tested first and final groups of four pulses in the same five sessions. Its result and off-shaft scope informed the present extension to all eligible pulses and a far-index-lag score. The current result is not new independent patient evidence.
