Local field potential oscillations as a cortical soliloquy.
Mann EO., Paulsen O.
Synchronized network activity can be recorded as fluctuations in the local field potential (LFP). In this issue of Neuron, Fröhlich and McCormick suggest that cortical LFPs themselves contribute to synchronization of the very network that generates them. Thus, in monitoring these brain waves, we may be listening to the cortex talking to itself.
