adults during auditory and visual oddball tasks, showing for both modalities similar overall ACC activation, the main contributor of N2b, but modality-specific connectivity to primary auditory (Heschl’s gyrus) and visual (striate) cortices (Crottaz-Herbette and Menon, 2006). These findings suggest top-down attentional modulation of sensory processing by ACC, which may be compromised in schizophrenia.
