C. elegans Touch-Withdrawal Circuit — Oscilloscope & Signal-Flow View

2D oscilloscope-and-circuit view of the C. elegans gentle-touch escape circuit: leaky integrate-and-fire sensory and command interneurons wired with real synaptic anatomy, plotted as live membrane-potential traces, a signal-flow diagram and a body contraction wave.

This is the 2D counterpart of the 3D C. elegans touch-withdrawal simulation: the same nine leaky integrate-and-fire neurons, the same real synaptic wiring, and the same conduction delays and refractory periods — but instead of an orbiting 3D scene, the circuit is read the way an electrophysiologist actually reads a circuit: as scrolling voltage traces on an oscilloscope. A 9-channel strip chart plots every neuron's membrane potential against threshold in real time with spike ticks, a signal-flow diagram below it shows synaptic pulses traveling along excitatory and inhibitory connections as they fire, and a body-wave strip at the bottom turns the resulting backward/forward command imbalance into a traveling contraction wave, exactly mirroring how a real nematode reverses from a head touch or accelerates forward from a tail touch.

⚙ Under the hood

Watch the C. elegans gentle-touch escape circuit as a live 9-channel oscilloscope: leaky integrate-and-fire neurons wired with real synaptic anatomy plot their membrane potentials in real time, a signal-flow diagram shows synaptic pulses traveling the circuit, and a body strip turns backward/forward command drive into a genuine contraction wave.
