The Evolution in Freely-Behaving Imaging and Optogenetics Technology
To offer neuroscientists the ability to stimulate and visualize individual neurons in freely-behaving animals, Mightex’s engineers went back to the drawing board and pioneered a new path in the in vivo calcium imaging field. Instead of miniaturizing and placing the microscope on the animal – thereby limiting the microscope’s features and the animal’s behaviour – we kept the microscope off the animal’s head by using an imaging fiber.
By keeping the microscope away from the animal’s head, the OASIS Implant accomplishes 2 main goals:
OASIS Implant Key Features
Investigate Multiple Brain Regions Simultaneously
Neurons project to different parts of the brain, and neuroscientists are interested in understanding how these connections affect behaviour. The OASIS Implant uses a bifurcated imaging fiber that connects to multiple GRIN lenses, allowing researchers to perform imaging and optogenetics in multiple brain regions simultaneously.
Manipulate Functional Neuronal Activity with Cellular-Resolution Optogenetics
To dissect neural circuits at the level of individual neurons, neuroscientists need a tool to perform cellular-resolution optogenetics in freely-behaving animals. The OASIS Implant uses Mightex’s Polygon DMD Illuminator to illuminate individual neurons in vivo.

Fiber Photometry and Cellular-Resolution Calcium Imaging with One System
The OASIS Implant is capable of both population-level calcium imaging using fiber photometry and cellular-resolution calcium imaging. Perform exploratory research using fiber photometry, and delve in deeper to understand the patterns of individual neuron firing.
Micro- to Meso-Scale Imaging and Optogenetics
The OASIS Implant enables neuroscientist to perform imaging and optogenetics with cellular-resolution in a deep-region of the brain, or image a large cortical region and stimulate specific populations of neurons (0.5mm to 3.2mm FoV).
Link Neural Activity and Behaviour
Neuroscientists are interested in linking brain activity and behaviour. Using the OASIS Implant, imaging and optogenetics data can be synchronized with external behaviour cameras and behaviour equipment using the included IO control box to link neural activity and behavioural events.
