A stereomicroscope, sometimes called a dissecting microscope or a binocular inspection microscope, is a low-power compound instrument used for a closer examination of three-dimensional specimens than is possible with a hand lens.
The main purpose of a stereomicroscope in neuroscience is to examine the surface of brains, tissue slices, or large neural structures. It is especially useful for the fine manipulation needed during dissections, surgeries, or the fabrication of small tools such as electrodes or implants
