By measuring brain signals, a neuroscience research group at the University of Tübingen has demonstrated for the first time that corvid songbirds possess subjective experiences. Simultaneously recording behavior and brain activity enabled the group headed by Professor Andreas Nieder to show that crows are capable of consciously perceiving sensory input. Until now this type of consciousness has only been witnessed in humans and other primates, which have completely different brain structures to birds. "The results of our study opens up a new way of looking at the evolution of awareness and its neurobiological constraints," says Nieder. The study has been published in the journal Science on September 24, 2020.
