Wistar rats compared to pigmented Long-Evans rats

- Motion perception was tested in pigmented Long-Evans and albino Wistar rats (Rattus norvegicus sp.) using moving
random dot patterns. Pigmented as well as albino rats could distinguish a fully coherently moving pattern from
dynamic noise. However, motion coherence thresholds were significantly lower in pigmented compared to albino rats
(12% and 30% coherence, respectively). These results indicate that pigmented rats have well developed motion coherence
perception, whereas albino rats are severely impaired but not motion blind.
