Optical Imaging and Stimulation Systems

OASIS (Optical Activation, Stimulation, and Imaging Systems) are ground-breaking platforms for all-optical cellular-resolution optogenetic stimulation and calcium imaging in vivo, both freely-behaving and head-fixed. With an OASIS, researchers can optogenetically and/or image 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 stimulation & imaging, and cortical neural circuitry mapping etc.

Target Applications

GCaMP imaging in the striatum of a mouse with a 600um field of view using the OASIS Implant.

This video shows the OASIS Implant being used in combination with the laser Polygon400 to deliver targeted optogenetic stimulation to different parts of the cortex of a freely-behaving mouse that in turn elicits different behaviours (Courtesy of Dr. Zhigang He and Noaf Alwahab, Harvard Medical School).

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.
