Video-rate volumetric neuronal imaging using 3D targeted illumination [PDF]

open access: yes, 2018
Fast volumetric microscopy is required to monitor large-scale neural ensembles with high spatio-temporal resolution. Widefield fluorescence microscopy can image large 2D fields of view at high resolution and speed while remaining simple and costeffective.
