  1. Results from unilateral FVEPs from six horses at two separate recording sessions months apart. Mean ± SD for first and second sessions. A paired t-test was used to compare results from the two sessions, p-values< 0.05 were considered statistically significant. Coefficients of variation (CV), coefficients of repeatability (CR) and intraclass correlation coefficients (ICC) are reported
