Motion Perception in Rats (Rattus Norvegicus Sp.): Deficits in Albino Wistar Rats Compared to Pigmented Long-Evans Rats

D Hupfeld et al. Behav Brain Res. .

Abstract

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.
