Researchers have recently discovered that mice exhibit behavior resembling self-recognition in mirror tests. 
Observations
The study found that black-furred mice, when marked with white ink on their foreheads, spent more time grooming themselves in front of a mirror, indicating an awareness of their altered appearance. However, this self-recognition-like behaviour was observed only in mice accustomed to mirrors, those who socialised with similar-looking mice, and when the ink spot was relatively large.
Findings
The study identified a specific subset of neurones in the hippocampus responsible for developing and storing visual self-images, providing insights into the neural mechanisms of self-recognition—previously a mystery in neurobehavioral research.
Despite the mice displaying behaviour indicative of self-recognition, the researchers emphasise that this doesn’t necessarily imply full “self-awareness.”
Future research
The study opens avenues for further exploration, including investigating the importance of visual and tactile stimuli and studying other brain regions involved in self-recognition.
