Abstract:
Though recent studies have shown that rodents express
emotions with their face, whether emotional expression in rodents has
a communicative function between conspecifics is still unclear. Here,
we demonstrate the ability of visual recognition of emotional
expressions in laboratory rats. We found that Long-Evans rats avoid
images of pain expressions of conspecifics but not those of neutral
expressions. The results indicate that rats use visual emotional
signals from conspecifics to adjust their behaviour in an environment
to avoid a potentially dangerous place. Therefore, emotional
expression in rodents, rather than just a mere 'expression' of
emotional states, might have a communicative function.
