Not all rats like to be tickled but by listening to their vocalizations it is possible to understand in real-time their individual emotional response, according to new research by the University of Bristol. The study, published today in Current Biology, suggests that if this same relationship is observed for other situations, then it may be possible to use call patterns in rats to measure their emotional response and understand how best to improve their welfare.
