Interactive Simulations

Classic models of neurons and plasticity, rebuilt from the original equations so you can run the experiments yourself.

Episode 01

Hodgkin–Huxley, 1952

The squid giant axon model run from the original equations and constants. Repeat the voltage-clamp protocols from the five 1952 papers and watch the action potential emerge.

Episode 02

One Burst per Song: HVC's Ultra-Sparse Code

In the zebra finch, each HVC neuron that projects to RA fires a single precise burst per song motif. Rebuild that ultra-sparse time code from Hahnloser, Kozhevnikov & Fee (2002) and watch RA read it out.

Izhikevich Neurons

Two equations, many firing patterns: tune the parameters of the Izhikevich model and switch between regular spiking, bursting and chattering neurons.

Spike-Timing-Dependent Plasticity

Pair pre- and postsynaptic spikes at different delays and watch the synapse strengthen or weaken under the STDP learning window.
