In Vivo Imaging and Stimulation Systems

OASIS (Optical Activation, Stimulation, and Imaging Systems) are ground-breaking platforms for all-optical calcium imaging and optogenetic stimulation in vivo, both freely-behaving and head-fixed. With an OASIS, researchers can image and/or optogenetically stimulate single cells, multiple cells, and/or multiple areas simultaneously in the brain of an awake animal. The fully reconfigurable and futureproof design of the OASIS platforms makes them suitable for a wide range of in vivo applications, such as deep-brain imaging & stimulation, and cortical neural circuitry mapping etc.

Are you interested in all-optical methods for probing in vivo neural activity and deciding what tool is right for you?

This paper will discuss several tools that enable in vivo calcium imaging and optogenetics and their relative merits in an experimental setting. Specifically, the advantages and drawbacks of two-photon imaging, head-mounted microscopes, fiber photometry, and fiberscopes for in vivo imaging and optogenetics will be discussed. Read more.
