Miniscope V4 uses wide-field fluorescence imaging to record neural activity in awake, freely moving mice. V4 miniscopes from LabMaker come fully-assembled, tested, and ready to use. The V4 is a leap forward in miniscope technology. It will serve as the platform for a new generation of miniscopes for years to come. This high-end solution will help to advance and disseminate miniature microscopy to the fast increasing open-source neuroscience community.
