Cardiac Action Potential
FitzHugh–Nagumo/Noble-style cardiac toy: fast upstroke, plateau-like repolarization, refractory recovery gate, and S1-S2 premature-stimulus capture vs block.
Nernst Potentials & Membrane
Nernst E for K⁺ and Na⁺ from inside/outside concentrations; optional Goldman–Hodgkin–Katz resting estimate.
Calcium Waves / IP3 Oscillator
Li-Rinzel-style IP3 receptor oscillator: cytosolic Ca, ER store, calcium-induced calcium release, SERCA refilling, flux traces, and a Ca–h phase portrait.
Hodgkin-Huxley / FHN Neuron Network
Multi-node excitable network using FHN reductions of HH dynamics: chain/ring topology, sigmoidal synaptic coupling, propagation delay, pacer-driven waves, and bursting-like activity.
Cable Equation on an Axon
1D passive cable ∂V/∂t = D∂²V/∂x² − (V−V_r)/τ + I; compare uniform fiber vs myelinated (higher D in internodes).
Coupled FitzHugh–Nagumo Neurons
Two excitable FHN units with diffusive coupling: phase plots, time traces, and synchronization vs coupling strength.
