Why this track exists
A closed-loop system cannot score above its recording floor. Signal quality is the baseline precondition for every downstream claim.

Only rows with run status published, provisional, or scored appear.
Metric definitions
| Metric | Description | Direction | Unit |
|---|---|---|---|
| Spike SNR | Median spike signal-to-noise ratio across active channels. | higher_better | dB |
| Active channel ratio | Fraction of electrodes with at least one detected unit. | higher_better | ratio |
| Sorted units per array | Number of well-isolated single units after spike sorting. | higher_better | units |
| ISI violation rate | Fraction of inter-spike intervals below the refractory threshold. | lower_better | ratio |
Scoring formula
Composite of normalized SNR, active-channel ratio, and spike-sorting unit yield. Equal weights per sub-metric, clipped to [0, 1].
