Directional motion asymmetry in infant VEPs--which direction?
Monocular viewing during early infancy reveals asymmetries in optokinetic nystagmus (OKN) and visual evoked potentials (VEPs). This study investigates the VEP asymmetry to see if it is consistent in direction with the OKN asymmetry. Steady-state VEPs were recorded from infants (5-21 weeks) viewing gratings that underwent successive displacements in the same direction, leftward or rightward. In addition, transient VEPs were recorded to the two directions of an oscillating stimulus. Both tests ...Expand abstract
