Waveforms of the five midline electrodes (Fpz, Fz, Cz, Pz and Oz) and the topological distribution of the difference wave components reflecting stimulus change detection (MMN and LDN) for attended (left column) and unattended (right column) stimuli across ages (YC = Younger Children, OC = Older Children, YA = Younger Adults, OA = Older Adults). Note that the LDN wave for attended stimuli contains two subcomponents with frontal and parieto-occipital maxima.
