Figure 3.
Grand average motion VEPs in full-term infants at 3–4 months (A) and 11–12 months (B), and in preterm infants at 3–4 months (C) and 11–12 months (D). Amplitudes are on the y-axis and latencies on the x-axis. The actual N2 peak latencies for forwards optic flow are indicated at PO4 in full-term infants and POz in preterm infants. Differences in N2 peak latencies for the three motion conditions were observed only in full-term infants at 12 months where latency increased from forwards optic flow to reversed optic flow and random motion.
