High-speed, multi-Z confocal microscopy for voltage imaging in densely labeled neuronal populations
biorxiv(2021)
摘要
Genetically encoded voltage indicators (GEVIs) hold great promise for monitoring neuronal population activity, but GEVI imaging in dense neuronal populations remains difficult due to a lack of contrast and/or speed. To address this challenge, we developed a novel confocal microscope that allows simultaneous multiplane imaging with high-contrast at near-kHz rates. This approach enables high signal-to-noise ratio voltage imaging in densely labeled populations and minimizes optical crosstalk during concurrent optogenetic photostimulation.
### Competing Interest Statement
JM, TDW, and Boston University have a US patent filed (#11,042,016) that relates to multi-plane confocal imaging.
