Cortical sources for the Nc (negative-central) ERP (event-related potential) in infants. The sources for the Nc ERP component are shown and occur over a wide range of ages in the prefrontal cortex (top left). The bottom left diagram shows the activity of the brain areas to a novel stimulus presented during sustained attention or when the infant is inattentive. The right-hand images show common brain locations for the oddball procedure and a paired-comparison procedure for infants at 20 weeks (4.5 months) and 32 weeks (7.5 months) of age.
