What are the main tests used in this study?
The main tests include the challenging beam traversal test, spontaneous activity assessment in a cylinder, and the adhesive removal test (DOT test).
How do these tests compare to automated methods?
These tests are more sensitive to motor dysfunction and are significantly more cost-effective than automated methods.
What is the purpose of the beam traversal test?
The beam traversal test is designed to assess the motor function of mice and their ability to navigate a beam under varying conditions.
How is spontaneous activity measured?
Spontaneous activity is measured by placing a mouse in a cylinder and recording the number of rears it makes during a set period.
What are the advantages of these behavioral assays?
The assays are highly sensitive, cost-effective, and provide reliable measures for evaluating potential therapeutics in movement disorders.
Can these tests be used for genetic mouse models?
Yes, these tests are effective for characterizing sensorimotor function in novel genetic mouse models.
