All tools you need investigate from the smallest synapse to the largest brain slice
In neuroscience, you need the tools to investigate from the smallest synapse to the largest brain slice. HUYGENS offers you DECONVOLUTION for better resolution and less noise in your images. Uniquely, it conserves quantitative information in your images, enabling you to get true quantitative results. Did you also know that HUYGENS offers a comprehensive toolbox for object analysis and large data processing?

- Primary astrocytes were fixed and their membranes were permeabilized. Cytochrome C was labeled with a primary antibody and linked to Alexa-488 secondary antibody. (Alexa 488 is a STED compatible dye that emits in the same channel as the commonly used GFP). Primary astrocytes were fixed and their membranes were permeabilized.

- Confocal and CW (non-gated) STED (Leica SP8; 100% STED power) images were recorded sequentially.Confocal and CW (non-gated) STED (Leica SP8; 100% STED power) images were recorded sequentially.
- Available metadata was automatically loaded in from the native file-format. Additionally the following settings were set (for more information see STED-Deconvolution: Available metadata was automatically loaded in from the native file-format. Additionally the following settings were set (for more information see STED-Deconvolution:
- blurring is visible in the raw STED image (bottom left) common to all ungated (CW) STED recordings. STED immunity fraction was set to 5%. Huygens is now informed that the PSF has a broad base and will remove blurring accordingly.
- STED depletion factor was set to 30* STED depletion factor was set to 30
- Images were deconvolved using Huygens Express Deconvolution. Express deconvolution estimates the background and signal-to-noise levels from the images automatically, generating reliable care-free image restoration. Huygens Express used GMLE for STED deconvolution and CMLE for Confocal deconvolution.

Huygens Light Sheet Fluorescence Microscopy (LSFM) deconvolution option supports a range of light sheets types, such as a Gaussian-profile (incl. multiview and flat field), scanning beam, and scanning Bessel beam and lattice. Large LSFM data sets benefit greatly from Huygens efficient RAM use, robust deconvolution algorithms, and GPU acceleration. Huygens Light Sheet deconvolution involves a spatially variant PSF for correcting PSF differences due to changes in light sheet thickness and depth-dependent spherical aberration. Deconvolution can be combined with multi-view fusion, made extremely easy with Huygens Fuser.
