Rats Recognize Object as We Do? Study Implies Yes!

“Sight is such a spontaneous activity that we are unaware of the complexity of the brain mechanisms it implies. For instance, we easily recognize objects, which appear to look always the same, without realizing that we observe them from ever-changing points of view and that their image - the luminance profile cast onto the retina - varies significantly each time we look at them,” writes Medical News Today. “To maintain such ‘invariance’ in the shape, our brain performs procedures that extract from the two-dimensional image "key" visual information that enables us to recognize the object under any condition. Scientists believe that such ability belongs to humans and to other primates, but whether such ability may be applied also to other mammal species is still controversial.” Read more.
