Lambda waves in the neonate (author''s transl)]

Different types of sharp elements can be observed over the occipital regions from the 2nd postnatal week in the open-eyed child, with active eye movement but practically no body movement. Certain of these sharply localised elements in the occipital midlin are identical to adult lambda waves. Their early occurrence calls to mind the emergence of visual function and attention, these latter occurring at the end of the neonatal period between 7 and 9 days.
