Natural language → Brain simulation → 3D visualization.
Describe any real-world scenario. An LLM classifies which brain regions activate, a Brian2 spiking neural network simulates the neural activity, and a Three.js-powered 3D brain model lets you watch it unfold — all in your browser.
A multi-stage pipeline that transforms a sentence into a biologically-inspired spiking simulation, rendered in real time on a 3D brain model.

Interactive Three.js brain mesh with real-time glow, bloom rendering, and per-lobe coloring. Spike counters, HPA context, and event logs update live during playback.
An OpenRouter-backed LLM analyses your natural-language scenario and classifies which brain lobe activates, the dominant neuromodulator, its intensity, and the scientific rationale — all in a single structured response.
Biologically realistic spiking neural network engine. Per-lobe spike indices and timing for scientifically grounded simulation.
Dopamine, serotonin, cortisol — modeled as simulation metaphors. HPA axis context visualized live.
From a single sentence to a complete brain simulation and 3D visualization — fully automated, fully real-time.

CogniGraph is a pure educational demo. Outputs are for visualization and learning — not diagnosis or treatment. The modeled neuromodulators and stress-hormone axes serve as simulation metaphors, not clinical measurements. Live on Fly.io + Vercel.
