Burst and tonic responses are studied in a minimal model of thalamic circuit composed of a retinal spike train, a relay neuron and a reticular neuron. The integrate-and-fire-or-burst model is used to simulate the neurons. Cross-correlograms show that burst events are more reliable than tonic firings in stimulus transmission to the cortex, and may be capable of scanning the sensory spike train for certain temporal correlations. The effect of brainstem projections on thalamic bursts during wakefulness and the possible role of bursts in attention mechanisms are discussed
