The buoyancy levitation system for 2P neural imaging in freely-behaving mice. (a) Schematic of the buoyancy levitation system. Lower-right: A zoomed-in diagram of the mouse’s head with a 2P fiberscope and an additional weight. (b) Photograph of a mouse in an open arena with a head-mounted fiberscope, additional weight, and a balloon counteracting the weight. (c) Representative 2P image of neurons expressing GCaMP6m, obtained from a fiberscope.
