A. Time courses of the simulated cortical dipoles. B. Peak latencies of the simulated dipoles (solid lines) for each dipole–amplitude ratio, and recovered potential peak latencies (empty symbols) for each reference electrode. Despite a constant time course of the underlying dipoles, the recovered scalp latencies differ dramatically as a function of the amplitude ratio. C. Same information after CSD transform: The recovered latencies are in close agreement with the underlying dipole time course.
