[Open the instrument](https://matsuo-koya.github.io/music-in-the-body/)

MaleCNS v1.0の実接続構造から、停止するまで演奏を続けるブラウザ音楽作品です。オスのショウジョウバエの脳と腹側神経索を一つの人工的な動的ネットワークとして動かし、サティ、アンビエント、ミニマルの文法を通して和声、モチーフ、粒子音、身体パルスへ読み出します。

## Data and scientific scope

Source: [MaleCNS v1.0 download](https://male-cns.janelia.org/download/), `connectome-weights-male-cns-v1.0-minconf-0.5-significant-only.feather`.

The browser artifact retains connections with weight ≥ 5 and excludes self-connections. Exact provenance, transforms, counts, and SHA-256 values are stored in `data/processed/`.

Measured data consists of wiring and connection weights. Network dynamics, external input, visual pulses, `body-pulse`, harmony, rhythm, and timbre mapping are artificial. They are not recordings of neural firing or behavior. Display positions are a deterministic performance layout, not anatomical coordinates. Current readout groups are deterministic body-ID partitions rather than anatomical brain/VNC classes.
