NeuroExplorer

Watch how electrical signals travel through neurons — the fundamental process behind every thought, movement, and sensation.

Action Potential: An electrical impulse (~100 mV) that travels along the axon at speeds up to 120 m/s.

Saltatory Conduction: Signals "jump" between gaps in the myelin sheath (Nodes of Ranvier), dramatically increasing speed.

Synaptic Transmission: At the axon terminal, neurotransmitters are released across the synaptic cleft to the next neuron.

Neurotransmitters: Chemical messengers including dopamine (reward), serotonin (mood), GABA (inhibition), and glutamate (excitation).

Use the speed slider at the bottom to control animation speed. The 3D view shows a detailed neuron model with signal propagation.
