12 Simulations
⚡Action Potential
Hodgkin-Huxley single-neuron dynamics. Na⁺ / K⁺ channels visualized.
🌊Axonal Conduction
A FitzHugh-Nagumo cable carries the spike down the axon. Myelination yields saltatory conduction.
🔌Synapse
Excitatory and inhibitory transmission, EPSP/IPSP summation.
🌐Neural Circuit
100 leaky integrate-and-fire neurons. E/I balance toggles synchrony and chaos.
📈Brain Waves
α / β / γ / δ / θ rhythms. Arousal slider shifts the dominant band.
🔄Neural Synchrony
Kuramoto phase oscillators lock into a collective rhythm; tracked by the order parameter.
🔗Hebbian Plasticity
Co-firing strengthens connections. STDP timing window visualized.
👁️Receptive Field
Gabor filters apply V1 edge detection to images in real time.
📊Perceptron
Two-class learning visualized step-by-step.
🧠Reinforcement Learning
A Q-learning agent solves a maze. Reward prediction error displayed.
✨Cognitive Illusions
Müller-Lyer, motion aftereffect, Stroop. Subject mode records reaction times.
💾Memory
Hopfield network recalls patterns from noisy input.
Highlights
Hierarchy
Single neurons → circuits → plasticity → network learning → cognition. The vertical stack of brain function in one app.
Clean UI
Material Design 3. Light / dark themes. 9 languages (JA, EN, DE, ES, FR, KO, PT-BR, Simplified & Traditional Chinese).
Faithful to the science
Hodgkin-Huxley, STDP, TD-error, Hopfield — textbook formulations, simplified for visual clarity.
