Linear dipole chain.

Schematic illustration of the model of a linear chain used in the dipole simulations. The dipoles are placed in the cortex with fixed coordinates (located in the calcarine sulcus, the extrastriate body area (EBA) and the superior temporal sulcus (STS)) and a randomized tangential orientation, which is held constant for each simulation. The time-dependent amplitudes of the dipoles are given by the time-course of a Rössler system.
