CNI 473 nanometer 1.5w laser for Confocal Light Field Microscopy(CLFM) The institute of Neuroscence, Chinese Academy of Sciences, presents a new imaging method, confocal light field microscopy, to enable fast volumetric imaging deep into brain. They demonstrated the power of this method by recording whole brain calcium transients in freely swimming larval zebrafish and observed behaviorally correlated activities on single neurons during its prey capture. Furthermore, they captured neural activities and circulating blood cells over a volume ⌀ 800 μm x 150 μm at 70 Hz and up to 600 μm deep in the mice brain.
