According to foreign media reports, most rat lovers know that mice seem to like to be tickled and laugh when stimulated. However, it turns out that this is not a generalization of all mice. Researchers from the University of Bristol in the UK conducted further research on the laughing rat phenomenon to determine whether the rodents really like to be tickled. “The researchers found that not all mice like to be tickled, and that some mice make a lot of calls, while others don’t, which are directly related to their emotional experience,” the University of Bristol said in a statement on Monday The mice that laughed the most had the highest positive emotional response to tickling.

Emma Robinson, a psychopharmacologist and lead researcher at the University of Bristol, said: “we show in this study that the sounds made by mice when they tickle accurately reflect their emotional experience, which is easy to measure.” Apple extends AppleCare + purchase period: users can decide within 60 days
