Preprint is out! Our BakingTray software turns a 2-photon microscope into a serial-section tomography system for automated whole-organ imaging. ~€35k to convert an existing scope. 11 systems worldwide, >7,000 samples at SWC alone #neuroskyence #microscopy www.biorxiv.org/content/10.6...
A BrainSaw at the Max Planck Institute for Brain Research, Frankfurt. A Nikon 16x water-immersion objective on a 400 µm travel PIFOC allows for fast z-stacks. Samples are imaged and cut in the clear water bath. A Leica VT1000 vibratome is seen to the right with a mounted blade.How BrainSaw works. Samples are embedded in an agarose block, which is glued to a slide and clamped into a water bath. The bath sits on a three-axis stage under a 2-photon microscope; the stage moves the sample for both tile scanning and slicing. The microscope images the exposed face of the block, the vibratome cuts off the imaged layer, and the cycle repeats until the samples have been fully imaged. Data are stitched automatically and are ready for downstream analysis. Logos below: BrainSaw (hardware), BakingTray (acquisition software), StitchIt (stitching).Coronal section of an Sst-tdTomato mouse brain imaged on BrainSaw. tdTomato-expressing cells are shown in yellow, scattered through cortex and hippocampus; tissue autofluorescence is shown in blue.Coronal section of a mouse brain with three neighbouring viral injections targeting layer 5 of V1, expressing mCherry (red), eGFP (green) and BFP (blue). The thick apical dendrites of the labelled neurons are clearly visible, as are their axons projecting to distant targets. Image credit: Alex Fritzl.

Single-cell electroporation is performed via patch pipette and under 2-photon visual guidance in vivo. A short voltage pulse train is applied through the pipette to deliver RNA molecules into a targeted cell. The video below shows this process in cortical neurons expressing GCaMP6s.
