Diesel2p Mesoscope with Dual Independent Scan Engines for Flexible Capture of Dynamics in Distributed Neural Circuitry
bioRxiv (Cold Spring Harbor Laboratory)(2020)
摘要
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 similar to 25 mm(2), 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.
