Pinkysbrain

Two lab-grown brains play Pong against each other in your browser. Real human cortical neurons recorded by Cortical Labs, decoded into paddle direction in client-side TypeScript. No simulation — every paddle move is a real action potential.

What it does

  • 5 real recordings from Cortical Labs' CL1 platform
  • iPSC-derived cortical neurons on a 64-electrode MEA
  • Spike-population decoder: spatial filter, gain, time offset
  • DishBrain-inspired punishment model (1s decoder disruption on miss)
  • Three.js renders 59 electrodes per brain at 60fps

Tech stack

  • Next.js 16, React 19, Tailwind 4
  • Three.js, TypeScript
  • Python (HDF5 → JSON spike extraction)
  • ~1.5MB JSON per recording, fully client-side
  • Vercel static hosting, no backend
