  1. Electroretinographic (ERG) response amplitudes (mean ± SD) obtained under various stimulus conditions in unaffected control and naturally scrapie-affected sheep. wL: white light stimuli on light-adapted eyes; blD: blue light stimuli on dark-adapted eyes; wD: white light stimuli on dark-adapted eyes. Level of significance *P < 0.05, **P < 0.01.
