Prof. Kozorovitskiy (Neurobiology) studies neuromodulation and plasticity in the striatum and basal ganglia, with a distinctive emphasis on developing and applying advanced optical imaging methods. Imaging technique innovations: (1) Oblique plane illumination (OPI / scanned oblique plane illumination, SOPi) microscopy — a single-objective light-sheet technique achieving tilt-invariant volumetric imaging for rapid 3D capture of fluorescently labeled neural structures without mechanical tilting; (2) Two-photon fluorescence imaging and two-photon glutamate/neuromodulator photorelease for single-synapse resolution in live tissue; (3) Near-infrared genetically-encoded calcium indicators (with Verkhusha group) for in vivo multi-color neural recording with reduced photobleaching. The lab's technical contributions are centered on extending the spatial and volumetric resolution of live-tissue fluorescence imaging. Irving M.
