To visualize neuronal structure and function in the physiological context, optical microscopy that is non-invasive and capable of resolving sub-cellular structures has become the method of choice. Structured illumination microscopy (SIM) is a widefield fluorescence imaging technique that optically sections 3D samples, but its applications have been usually limited to in vitro samples. To apply SIM to in vivo imaging, we modified optical-sectioning SIM reconstruction algorithm and incorporated adaptive optics. We demonstrated fast, high-resolution in vivo imaging with optical sectioning for structural and functional interrogations of the brain in vivo.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
