Event Horizons of Neural Spikes
Extracellular spike-event codec · ZPE-Neuro · PyPI zpe-neuro v0.1.1 · github.com/Zer0pa/ZPE-Neuro
A neuron fires when the voltage crosses a threshold — not before, not after. At that exact moment, a spike exists. Extracellular recordings catch millions of those crossings and return them as gigabytes of raw voltage.
ZPE-Neuro works at the threshold: it extracts spike events on DANDI 000034 at 481× event-ratio compression and 74.44 µV residual, then replays them bit-identical across five seeds. The window is bounded. The crossing is precise. Latency is a modeled cycle figure, not measured on silicon. Breadth beyond 000034 stays open.

Brain recordings come back as raw voltage. the spike events inside them have no standard archive.
A spike is not the whole recording. it is the event the archive can keep.
Extracellular pipelines usually keep voltage first and derive spike events later. That preserves the full trace, but it leaves every threshold crossing buried inside large files, local preprocessing choices, and dataset-specific scripts.
ZPE-Neuro extracts threshold crossings into a deterministic event stream. On the declared DANDI 000034 window, it reports 481× event-ratio compression, 74.44 µV residual, and 5/5 bit-identical replay across random seeds. Breadth beyond that window remains open.
Every claim stays inside DANDI 000034. breadth beyond the window is still open.
Five random seeds, five bit-identical spike-event streams.
Deterministic means one narrow thing here. On DANDI 000034's declared window, the spike-event extractor emits bit-identical event streams across five random seeds — 5/5 SEEDS measures that. Extracted events are the threshold crossings; the voltage between them is gone. Latency is a modeled cycle figure at 80 MHz ARM-class clock, not measured on silicon. Check D modeled mean 612.5 ns, p99 850 ns, against a 900 ns proxy threshold. No on-silicon determinism claim follows.
DANDI breadth MISS: 1 of 2 counted targets; DANDI 000003 ran and failed, IBL remains unclosed. Latency is hardware-proxy modeled, not silicon. PR #52 is draft, not on main. PyPI v0.1.1 is stale. README still carries a private staged badge. No clinical or diagnostic claim is made.
ONE SPIKE EVENT opens five paths.
The aim is not a general neural decoder. It is one thing well: a threshold crossing that survives encode, compress, and replay unchanged. Applied across datasets, that discipline turns extracellular archives from raw voltage dumps into objects two labs can point at and mean the same event.
