摘要：
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. (c) 2006 Elsevier B.V. All rights reserved.
