Man or woman, happy or sad. Sometimes a glance is enough to say it. Yet, the visual process that allows us to recognize the gender or emotional state of a person is very sophisticated. Until recently, only primates were deemed able to perform such complex operations as object recognition. A new study from SISSA, published in the journal Current Biology, shows that rodents also use advanced and diversified object recognition strategies. These results confirm the validity of this animal model for the study of object vision and offer new opportunities for the development of artificial vision systems and diagnostic approaches.
