Topographical scalp distributions of the N1 ERP component in response to 0, 50, 100, 200 and 400 cents pitch shifted voice feedback at vocal onset. The top and bottom rows show the topographical maps of N1 distributions for active vocalization and passive listening conditions, respectively. The maps are calculated for 13 recording sites on the surface of the scalp (C_Z, C₃, C₄, T₇, T₈, F_Z, F₃, F₄, F₇, F₈, P_Z, P₃, P₄).
