Measuring Preweaning Sensorial and Motor Development in the Mouse

Area of Science:

• Developmental biology
• Neuroscience
• Animal models

Background:

• Mouse ontogeny offers a model for studying developmental processes due to immaturity at birth.
• Assessing developmental rates requires precise control over conceptional or chronological age.
• Non-invasive methods are crucial for longitudinal studies of development.

Purpose of the Study:

• To establish standardized protocols for measuring sensory and motor development in mice.
• To enable the validation of murine models for human developmental disorders.
• To facilitate comparative analyses of developmental trajectories.

Main Methods:

• Development of 18 non-invasive measures for sensory and motor milestones from birth to weaning.
• Establishment of protocols for producing mice with known ages.
• Implementation of pup identification methods for follow-up studies.
• Description of testing procedures for newborn mice's abilities.

Main Results:

• A comprehensive set of 18 developmental measures was detailed.
• Protocols for age standardization and pup identification were provided.
• The described methods support longitudinal developmental assessments.

Conclusions:

• The developed protocols provide a framework for studying mouse development.
• These methods are essential for validating mouse models of human developmental disorders.
• This work facilitates research into neurodevelopmental conditions using animal models.
