Figure 2.

Waveforms of the five midline electrodes (Fpz, Fz, Cz, Pz and Oz) and the topological distribution of the ERP components (N1, P2, and N2) for deviant (left column) and standard (right column) stimuli under Unattend condition across ages (YC = Younger Children, OC = Older Children, YA = Younger Adults, OA = Older Adults). Note that under Unattend condition ERPs are reduced to three early components (N1, P2, and N2) and the later components (P3 and N3) appear in a redundant form or failed. Note also that the brain maps have different scaling.
