News, Outreach
We were watching the solar eclipse in the United States together with the lab. Here are some pictures of us using a telescope and one of the most important tools in an optics lab to visualize the sun – an ND filter. [gallery type="slideshow" ids="1958,1957,1956,1955"]

Our paper entitled “Video rate volumetric Ca2+ imaging across cortical layers using Seeded Iterative Demixing (SID) microscopy” has been published in Nature Methods. We present a novel computational technique termed Seeded Iterative Demixing (SID) that allows for capturing neuronal dynamics in vivo within a volume of 900 × 900 × 260 µm, located as deep as 380 µm in the mouse cortex and hippocampus, and at a very high volume rate of 30 Hz. SID is based on Light Field Microscopy (LFM), a 3D imaging technique that our group has established in a previous publication as a versatile neural recording technique for weakly scattering specimen, such as larval zebrafish. SID extends LFM into more strongly scattering tissue such as the mammalian cortex by seeding a machine learning algorithm with remaining…
