Action Potential Cascade
The Electrical Language of Neurons
Voltage-gated ion channels regulate the flow of Na+ and K+ ions across the membrane. When a threshold is reached, an explosive localized depolarization occurs—the action potential.
Probabilistic Transmission
Neurotransmitter particles undergo random walk diffusion after release. Each particle has a probability of activating a nearby dendrite when it comes close enough. This stochastic element captures a key feature of biological synapses: transmission is inherently probabilistic, not deterministic.
