Behavioural Changes in Mice after Getting Accustomed to the Mirror.

Area of Science:

• Cognitive Neuroscience
• Animal Behavior Studies
• Comparative Psychology

Background:

• Inability to recognize self in mirrors is observed in patients with neurological disorders like stroke and dementia.
• Investigating mirror image recognition in animal models is crucial for understanding its underlying psychological and biological mechanisms.
• Current research lacks clarity on suitable animal species and the specific mechanisms involved in mirror image recognition.

Purpose of the Study:

• To investigate whether mice possess the ability to recognize their own mirror images.
• To establish mice as a model organism for studying the cognitive and biological basis of self-recognition.
• To explore the behavioral responses of mice to mirrors and their own reflections.

Main Methods:

• Behavioral experiments were conducted to assess mice's interest in mirrors versus live stranger mice.
• Mice were observed with and without plastic tape on their heads to gauge reactions to their reflections.
• Familiarization with mirrors and testing with photos of self, strangers, and cage-mates were employed to evaluate recognition capabilities.

Main Results:

• Mice showed a stronger preference for live stranger mice over mirrors.
• Mice exhibited increased time spent in front of mirrors when marked with tape on their heads.
• Mice accustomed to mirrors demonstrated enhanced interest in photos of themselves compared to others, indicating recognition of the tape on the reflected image.

Conclusions:

• Mice can visually recognize objects (like tape) attached to their reflected images.
• Mice accustomed to mirrors can discriminate between their own reflections, cage-mates, and stranger mice.
• While mice recognize visual discrepancies in their reflections, it remains undetermined if they possess true self-recognition.
