  1. FVEP triplicates from one randomly selected eye in each of 17 horses were evaluated in a nested mixed-model with random effects. Some wavelets were detected in all recordings, whereas others only in some replicates. Mean, intra-individual and inter-individual SD (SDintra-individual, SDinter-individual), as well as intra-individual and inter-individual coefficients of variation (CVintra-individual and CVinter-individual respectively) are reported for each parameter
