Pain is an important physiological response triggered by physical injury or psychological stressors. While studies have shown that mice housed with mice experiencing pain show heightened pain sensitivity, underlying mechanisms remain unclear. A new study by researchers from Tokyo University of Science finds that exposure to stress calls emitted by mice experiencing pain triggers pain and inflammation in naïve mice, thus providing novel insights into pain perception and its social transmission.
