# ZAPBench
**Entity class:** Concept or analytic term
**Domain:** Whole-Brain Activity Modeling / Functional Connectomics
**Doc Type:** Dataset and Benchmark Node
**Maturity:** Published activity benchmark; aligned connectome remains a separate completion claim
**Primary Source:** [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]]
## Definition
**ZAPBench**, the Zebrafish Activity Prediction Benchmark, is a whole-brain neural-activity dataset and predictive-model benchmark based on larval zebrafish responding to controlled virtual environments. Its scale is approximately the full neuronal population of the small vertebrate brain.
## Benchmark role
Models receive recent activity and are evaluated on their ability to predict held-out future neural activity. The design allows activity-only models to be compared with models that incorporate structural connectivity when the aligned connectome is available, making the value of wiring information empirically testable.
## Comparative position
[[wiki/MICrONS|MICrONS]] offers dense structure-function registration in a mammalian cortical volume; ZAPBench pursues whole-brain functional coverage in a much smaller vertebrate. [[wiki/FlyWire|FlyWire]] supplies whole-brain structural completeness in an insect. These are complementary scale choices, not a single linear ranking.
## Evidentiary boundary
Whole-brain recording does not equal perfect measurement, and an activity benchmark is not the same thing as a completed synapse-resolution connectome. Predicting neural dynamics supports model comparison without proving subjective experience, behavioral equivalence, or continuity.

- **INF-0127 — Strongly indicated.** Benchmarking whole-brain activity prediction in larval zebrafish turns emulation from an argument into a leaderboard. Once a capability has a benchmark, it acquires a measurable improvement rate, and measurable improvement rates end debates about feasibility.
