Mission

The ‘mesoscale selective plane illumination microscopy’ (mesoSPIM) initiative aims to provide the imaging community with open-source light-sheet microscopes for large cleared samples. On the one hand, it is aimed at neuroscientists and developmental biologists seeking high-quality anatomical data from cleared samples, on the other hand, it strives to provide instrumentation developers with imaging platforms that can be tailored towards specific needs – i.e. to accommodate uncommonly large samples or different illumination schemes.

In addition, we foster interactions between the developers of clearing methods, instrumentation designers and users by organizing meetings and workshops.

History

In late 2015, the mesoSPIM project started as a tiny side project for Fabian Voigt when
Adriano Aguzzi (University Hospital Zurich) approached Fritjof Helmchen (Brain Research Institute, University of Zurich) with a request for help in the selection of a light-sheet microscope for CLARITY-cleared mouse brains. After some unsatisfactory tests of existing commercial setups, we decided to build our own. For more information on the mesoSPIM history, please visit the mesoSPIM wiki.

Team

image-leftFabian F. Voigt is a PhD student in the laboratory of Fritjof Helmchen at the Brain Research Institute, University of Zurich. As a BSc student in Interdisciplinary Science, Fabian started out building light-sheet endoscopes for in vivo calcium imaging in mice (miniSPIM). In his BSc thesis, he used electrically tunable lenses (ETL) for fast 3D two-photon imaging and later brought the technology to the lab of Jan Huisken at MPI-CBG in Dresden which resulted in the ETL-SPIM, a fast volume scanning light-sheet microscope. In his MSc studies at ETH Zurich, he designed two-photon mesoscopes. In a collaboration with the lab of Ursula Keller at ETH Zurich, he designed cost-efficient femtosecond semiconductor disk lasers and demonstrated their potential for multiphoton imaging. The mesoSPIM initiative is part of his PhD studies at the University of Zurich.

His research is focused on the development and application of optical methods, in particular two-photon microscopy, to study neural activity on the subcellular, cellular, and circuit level. His group has pioneered several microscopy techniques, including 3D, high-speed, and multi-area in vivo two-photon imaging, and has contributed to recent advancements in the study of cortical microcircuits. Fritjof Helmchen is currently Director of the Neuroscience Center Zurich
