Bursting arises when a fast spiking mechanism (Na⁺/K⁺ HH-like) is combined with a slow outward current (here, slow K⁺). During a burst, spikes activate the slow K⁺ current, which accumulates and eventually terminates the burst. During the silent phase, slow K⁺ deactivates, allowing the next burst. This rhythm appears in respiratory neurons, pancreatic β-cells, and thalamic pacemakers. The burst frequency depends on τ_slow; spikes per burst depends on the slow conductance strength.
