The adhesive removal test: a sensitive method to assess sensorimotor deficits in mice

Area of Science:

• Neuroscience
• Animal Behavior
• Surgical Procedures

Background:

• Long-term functional deficits after brain injury in mice are difficult to accurately assess.
• Current assessment methods may lack the sensitivity to detect subtle or specific deficits, leading to ambiguous conclusions about recovery.

Purpose of the Study:

• To present a detailed protocol for the adhesive removal test in mice.
• To establish a reliable method for assessing long-term functional deficits post-brain injury.
• To improve the sensitivity and specificity of behavioral tests in rodent models.

Main Methods:

• The protocol involves applying adhesive tape to the forepaws of mice.
• Key metrics measured are the time taken for the mouse to contact the tape and the time taken to remove it.
• A pre-surgical training regimen (1 week, daily trials) is recommended to optimize performance and reduce variability.

Main Results:

• The adhesive removal test assesses both sensory (time-to-contact) and motor/dexterity (time-to-remove) functions.
• This behavioral assay provides quantifiable data on fine motor skills and sensory perception in the forepaws.
• Training improves baseline performance and reduces inter-individual differences.

Conclusions:

• The adhesive removal test is a sensitive and specific assay for evaluating long-term functional deficits after brain injury in mice.
• This method offers a valuable tool for researchers studying neurological recovery and the efficacy of therapeutic interventions.
• Standardized training enhances the reliability of the test for assessing sensory and motor impairments.
