The Microdrill is made for cranial perforation function. It can be either a hand-held drill or fixed to the cranial drill holder of the stereotactic instrument, which makes it simple to operate and easy to master.
The elevated plus maze test is one of the most widely used tests for measuring anxiety-like behavior. The test is based on the natural aversion of mice for open and elevated areas, as well as on their natural spontaneous exploratory behavior in novel environments. This test has a strong validity profile for anxiolytic drug validation and screening. All open arms include 1cm high end plates to ensure the mice do not fall off the maze during exploration.
