We are excited to announce that Moculus is hitting the road for a special tour across the US and Japan in 2024!
Featured highlights:
To better understand brain functions during natural behavior, experiments that mimic the real world as closely as possible are essential. High-resolution studies require head fixation to the microscope, enabling subcellular imaging of thousands of cells with advanced 3D scanning and photostimulation, unlike free-running animal studies with limited FOV and resolution. Quality surgery allows studying these cells for months in experiments. Virtual-reality (VR), in combination with head-fixed recordings provides control and stability for recordings during behavioral experiments allowing the creation of complex interactive virtual environments. The Mouse Virtual Reality system provides the animal with the sensation that the virtual environment is reality, thereby achieving faster learning and lifelike imprinted behavior reactions.
Our patented comprehensive VR head-mounted display for mice provides binocular depth perception and stereoscopic 3D vision. By positioning the displays to the eyes of a head-fixed mouse running on a treadmill, virtual scenes can be displayed to the mouse in closed-loop experiments, where the treadmill motion controls the visual scene. This makes it possible to reproduce real, freely moving behavior tasks, whilst the high-resolution, large FOV or even 3D random-access microscope records the brain states on the cellular or subcellular level. The photorealistic rendering engine creates perspective corrected 3D virtual world and stereoscopic binocular vision in a large FOV, allowing full immersion in any imaginable environment
The biggest added value of Virtual Reality is the sense of presence, when the experimental animal perceives the widely controllable and reproducible virtual environment around it as reality itself.
