LFP and spike data of the model. Without stimulation, the troughs of the unpulsed V4 LFP (in grey) coincide with the peaks of the V1 population B (in red), hence suppressing the incoming information from B while "attending" to the signal carried by A. However, a pulse applied at the proper phase of the V4 LFP (marked in green), results in a phase shift of the LFP (in black). The troughs of the new LFP now coincide with V1 population A, thus effectively changing which input signal is gated/attended.
