A study at the University of Texas Southwestern Medical Center suggests mice can recognize themselves in a mirror, similar to a small group of mammals.

Mice familiar with mirrors and socialized with similar mice displayed behavior implying self-recognition when marked with visible ink.

The study identified neurons in the hippocampus involved in developing and storing visual self-image.

Mice who grew up with mirrors were more likely to recognize themselves compared to those without prior experience with reflective surfaces.

Specific neurons were found to be crucial for passing the Mirror Test and identify similar groups.

While cautioning against drawing conclusions about mouse consciousness, the study provides insight into the neural activity when mammals see themselves in a mirror.

The researchers also plan to investigate if mice can detect changes in their appearance using facial filters.
