An emergent concept in neurosciences consists in considering brain functions as
the product of dynamic interactions between neurons and glial cells, particularly
astrocytes. Although the role played by astrocytes in synaptic transmission and
plasticity is now largely documented, their contribution to neuronal network
activity is only beginning to be appreciated. In mouse olfactory bulb slices, we
observed that the membrane potential of mitral cells oscillates between UP and
DOWN states at a low frequency (
