Sept. 25 (UPI) — For the first time, scientists have observed conscious processes in the brains of crows. Until now, the neural origins of subjective experience have only been observed in humans and other primates.
“The results of our study opens up a new way of looking at the evolution of awareness and its neurobiological constraints,” lead researcher Andreas Nieder, professor of animal physiology at the University of Tübingen in Germany, said in a news release.
Previous brain imaging studies have shown the ability of humans and the primates to consciously perceive sensory input is located in the cerebral cortex.
But the brains of most animals are structured quite differently than those of humans and nonhuman primates. Most animals don’t have a cerebral cortex.
For the latest study, researchers in Germany wanted to determine whether conscious processes could originate brains without cerebral cortexes. To find out, scientists recorded the neural
