Rats trail behind shrews, monkeys, and humans in visual problem solving
Rats take a fundamentally different approach toward solving a simple visual discrimination task than tree shrews, monkeys, and humans, according to a comparative study of the four mammal species published in eNeuro. The work could have important implications for the translation of research in animal models to humans.
Scientists have developed powerful technologies that allow for precise manipulation of the rodent nervous system, which is similar to that of humans, making them crucial laboratory animals in neuroscience. Although it is thought that learning in mice and rats can overcome initial species differences on a task, few studies have directly tested this idea.
