Rats demonstrate advanced object recognition capabilities, challenging the notion that this is unique to primates. This review highlights their potential as valuable models for studying higher-level vision alongside monkeys.

Area of Science:

  • Neuroscience
  • Vision Science
  • Comparative Psychology

Background:

  • Invariant visual object recognition is crucial for understanding the environment.
  • Primate models have historically dominated research due to assumed superior visual processing.
  • Rodents, particularly rats, have been overlooked despite advancements in neuroscientific tools.

Purpose of the Study:

  • To review and summarize existing research on object recognition in rats.
  • To assess the capabilities of rats in advanced visual processing and shape perception.
  • To evaluate rats as potential complementary models to primates for higher-level vision research.

Main Methods:

  • Review of behavioral studies on rat pattern vision.
  • Analysis of recent investigations into rat object recognition and shape processing.
Keywords:
