Demos / Compiled brains

Fish in the Matrix.

Measured wiring. Connections that learn.

Teach a gaze circuit to hold, return, and hold again on the same brain.

Expand Teach this fish, choose hold your gaze and press Teach this lesson. Then teach let it return, and try holding again. The connections keep what they learned between lessons. Lessons run at 8×; the always-visible Time control lets you change the pace. Hover for help; drag to orbit, wheel to zoom.

The wiring

One cell, one patch.

The graph comes from a measured connectome. Cadence preserves its connection partners and synapse counts, then adds declared neuron and body models.

The fish

Two lessons, one brain.

Practice changes connection strengths in the gaze circuit using feedback from its activity. Pause learning keeps those changes; reset starts over. A fixed pilot supplies swimming, hunting and escape.

The larva

A whole-body circuit.

Switch to the Platynereis larva to explore how light and touch drive its compiled sensory and motor pathways. Its connections stay fixed.
