Cortical processing of visual motion in young infants

High-density EEG was used to investigate the cortical processing of a rotatirig visual pattern in 2-, 3-, and 5-month-old infants and in adults. Motion induced ERP in the parietal and the temporal-occipital border regions (OT) was elicited at all ages. The ERP was discernable in the 2-months-olds, significant and unilateral in the 3-month-olds and significantly bilateral in the 5-month-olds and adults. The motion induced ERP in the primary visual area was absent in the 2-month-olds and later than in the OT area for the 3-month-olds indicating that information to OT may be supplied by the VI bypass at these ages. The results are in agreement with behavioural and psychophysical. data in infants. (C) 2007 Elsevier Ltd. All rights reserved.
