Balanced excitation and inhibition: Model based analysis of local field potentials

► Local field potentials (LFPs) are generated by co-localised dipoles. ► The LFP model decomposes LFP into excitatory (E) and inhibitory (I) components. ► The LFP model can be used to investigate the balance of E/I. ► The balance of E/I is determined by the amplitude of E/I and their temporal lag.
