The computational role of the olfactory bulb remains a mystery after 60 yr of physiological research. Recently, Fantana and colleagues proposed a new model of bulb function based on sparse inhibitory connections between glomeruli, the functional units of the bulb, rather than the existing lateral inhibition model. I present a summary of their model here and its implications along with comparison to recent work in the very similar Drosophila olfactory system.
