Figure 6. Fitting of light-adapted ERG b-waves. A: Representative light-adapted b-wave fitting waveforms of midazolam, medetomidine, and butorphanol tartrate (MMB), pentobarbital sodium, and ketamine/xylazine (KX). Log light intensity at half maximum amplitude (K), log maximum amplitude (R_max), and n parameters of each group are shown in B, C, and D, respectively. Note that there were no statistically significant differences between the three groups.
