A novel behavioral paradigm using mice to study predictive postural control

Area of Science:

• Neuroscience
• Biomechanics
• Animal Models

Background:

• Postural control is crucial for maintaining balance against self-generated or external disturbances.
• Anticipation of predictable disturbances modulates postural responses, suggesting higher-level neural involvement.
• The neural circuitry underlying predictive postural control remains largely unknown.

Purpose of the Study:

• To develop a novel experimental paradigm for studying predictive postural control in mice.
• To enable future neural recordings and circuit manipulations in mice for postural control research.

Main Methods:

• A dynamic platform generated reproducible translational perturbations for mice standing on hind legs.
• Mice received auditory cues preceding predictable backward translations.
• Postural responses to predictable versus unpredictable perturbations were analyzed across multiple days.

Main Results:

• Preliminary results validated the novel experimental paradigm.
• The auditory cue's effect on postural responses was investigated.
• The paradigm successfully elicited measurable postural adjustments in mice.

Conclusions:

• The developed mouse paradigm is a viable tool for studying predictive postural control.
• This paradigm opens avenues for detailed neural investigation of balance and anticipation.
• Future research can utilize this model to explore the neural basis of predictive motor control.
