Summary
This study investigated lateralised behaviours in mice using three tests. Results showed paw preference and rotatory swimming tests correlated, suggesting links between lateralisation, emotions, and neural pathways.
Area of Science:
- Neuroscience
- Animal Behaviour
- Behavioral Neuroscience
Background:
- Lateralised behaviours, or the preference for using one side of the body, are common in many species.
- Understanding the reliability and underlying mechanisms of these behaviours is crucial for neuroscience research.
Purpose of the Study:
- To assess the reliability of lateralised behaviours across different experimental paradigms.
- To explore the relationship between lateralised behaviours and potential underlying emotional and neural factors.
Main Methods:
- BALB/c mice were evaluated using three distinct tests: the Collins paw preference test (PPT), the rotatory swimming test (RST), and the T maze test (TMT).
- Quantitative scores for lateralisation were recorded for each test.
Main Results:
- A significant positive correlation was observed between lateralisation scores obtained from the paw preference test (PPT) and the rotatory swimming test (RST).
- No significant lateralisation was detected in the T maze test (TMT).
Conclusions:
- The findings suggest that lateralised behaviours measured by the PPT and RST are reliable and potentially linked.
- The results support the hypothesis that lateralised behaviours are closely associated with emotional processes and specific neural pathways.
