نبذة مختصرة : Imaging the activity of neurons that are widely distributed across brain regions deep in scattering tissue at high speed remains challenging. Here, we introduce an open-source system with Dual Independent Enhanced Scan Engines for Large field-of-view Two-Photon imaging (Diesel2p). Combining optical design, adaptive optics, and temporal multiplexing, the system offers subcellular resolution over a large field-of-view of ~25 mm2, encompassing distances up to 7 mm, with independent scan engines. We demonstrate the flexibility and various use cases of this system for calcium imaging of neurons in the living brain.
Imaging of neuronal activity across distant brain regions is challenging. Here, the authors introduce a two-photon microscope with two independently controlled scan engines, and demonstrate calcium imaging with subcellular resolution in brain regions up to 7 mm apart simultaneously.
