Figure 2

Achromatic stimulation: neurofibromatosis type 1 (NF1) mean amplitude of the steady-state visual evoked potentials (VEPs) evoked by achromatic stimulation was not significantly different from control levels. (A and B) Grand averages of (A) elicited VEPs and (B) of the rectified VEPs used for analysis for each stimulus contrast used (labeled on the left) for the control and NF1 groups. Positive voltage is up. (C) Contrast response function of the mean amplitude of VEPs for the control (black open diamonds) and NF1 group (grey squares). All data are represented as mean ± 1 standard error of the mean.
