Neuroimaging Collaboratory

The Neuroimaging Collaboratory provides BHRI members with resources and support for advanced microscopy and image analysis.

RESOURCES:

*Please watch the "Special Webinar: Introduction to Light Sheet Microscopy with the UltraMicroscope Blaze" here: Special Webinar 

 

Training and Technical Support:

All users need to complete training on how to use the microscopes and/or computers prior to scheduling the use of equipment.

Training and technical support are provided by the Co-Directors Drs. Lique Coolen (Slide Scanner and MBF Bioscience) and Aleisha Moore (Light-sheet microscope).

Services are also available for the acquisition of pilot data, with imaging and capture conducted by the collaboratory technician or Co-Directors. 

Scheduling: 

After completing training, you will receive access to the Elan Infinity scheduling system.

To schedule use of any of the microscopes or computers, use: https://infinity.kent.edu/. 

How to schedule an instrument on Elan website (after completing training). If you have questions about Idea Elan scheduling or with any questions about navigating the scheduling system, please contact Lolita Winning  

User Fees:

We are in the process of developing a user fee-for-service cost structure, along with descriptive material about the Collaboratory, its equipment and facilities, for your use in grant applications. At the present time, usage will remain free of charge for all BHRI members. 

MICROSCOPES:

 

Olympus VS200 Research Slide Scanner: 

Keywords: high throughput, high speed, fluorescent, brightfield, deconvolution. 

slidescanner

The Slide Scanner is designed to capture high-resolution images of your microscope slides for quantitative analysis. The main advantages of the Slide Scanner are the automation, speed, and ease of capturing large numbers of images. Users can even set up their image-project and leave the Collaboratory to work on other tasks and return later to a full set of images captured automatically.

The slide scanner can capture brightfield and precise fluorescent signals (up to 5 channels: UV, green, red, far red, and near-infrared) with reduced photobleaching. Two slide trays are available for different sizes of microscope slides: 3"x 1" or 3" x 2" slides. A barcode reader automatically captures and records slide information and extensive metadata is available for optimal rigor and reproducibility. 

Images can include entire sections or regions of interest within sections. Z-stacks can be captured for the use of deconvolution software (see: Image analysis software). Image analyses can be performed with any software of choice, including Fiji and Imaris (see: Image analysis software). Examples of use: RNA scope or immunofluorescent analysis in multiple experimental groups; full brain analyses of brain area size and neuron morphology. 

Technical Details:

Filter sets for Fluorescence:  

  • DAPI Filter Set 350/50X, BS400, 460/50M 
  • EGFP/FITC/CY2 Filter Set 470/40X, BS495, 525/50M

Fluorescence and bright-field image capturing and analysis:

Keywords: fluorescent, brightfield, whole slide imaging, stereology, morphometric analysis.  ​ 

stereo-investigatorThis microscope can be used for a variety of projects, including traditional viewing and capturing images of fluorescent (up to 4 channels: UV, green, red, far red) and brightfield microscope slides. In addition, it contains multiple MBF Bioscience modules that allow for:

  • Whole Slide Imaging: Capturing many small high-resolution image tiles or strips and then montaging them to create a full image of a histological section. 
  • Morphometric and Stereological analyses 

 

MBF Bioscience Module Neurolucida is fully integrated with Leica DMR microscope system hardware to control motorized stage, focus, camera, and optical filters, and is used to capture high quality images and z-stacks of brightfield or fluorescent sections. A key feature is the ability to automatically capture and montage images at high magnification of a large area for high-quality images (whole slide imaging).

Neurolucida is also specifically designed for accurately tracing neuronal structures directly from histological specimens and generating quantitative morphometric data and is used for over 500 morphological quantitative analyses. Analysis can be completed on a separate computer in the collaboratory (see:Image analysis software). 

Stereo Investigator provides the means to make accurate, unbiased quantification of the number, length, area, and volume of cells, subcellular and macro structures in tissue specimens. The Stereo Investigator system makes stereology accessible, with easy-to-follow workflows with the most commonly used probes and clear quantitative results. Stereo Investigator can be used for analysis directly on the microscope system, from image stacks, or whole slide images on a separate computer in the Collaboratory (see: Image analysis software). 

Examples of use: optimization and validation of antibody staining, single images (or montaged images) of different experimental treatments, dendrite and spine analysis, stereological analysis.

Light-sheet Microscope: Miltenyi Biotec Ultra Microscope II 

lightsheet microscopeThis light-sheet microscope enables rapid 3D visualization of whole biological systems, including embryos, brain and other organs from a variety of animal models or human tissue samples. Homogeneous fluorescent excitation is achieved by six light sheets that illuminate the sample from both sides. Moving the sample through the light sheets allows the generation of sharp and bright 3D images. The light-sheet microscope is compatible with tissue clearing and imaging protocols performed using either aqueous-based solutions (e.g., CLARITY), or organic solvent-based solutions (e.g., 3DISCO, iDISCO). At present, this Light Sheet microscope is not available for training or for individual users, but can be used for acquisition of pilot data, with imaging and capture conducted by the collaboratory technician. 

 

IMAGE ANALYSIS SOFTWARE AND COMPUTERS:

The Collaboratory also includes two stations equipped with Dell computers loaded with image analysis software. These software packages can be used with images captured on the microscopes in the Collaboratory or other microscopes including any confocal or bright-field/fluorescent microscope:

 

  • Imaris (Bitplane) Imaris is the market-leading software for visualization and analysis of images collected from wide-field, confocal (including spinning disk), light sheet, two-photon, electron microscopy, CLEM, OPT, and other microscopes, with over 4,000 publications in 2020 alone.
  • Fiji (ImageJ)
  • Deconvolution software (Olympus)
  • Stereo Investigator (MBF Bioscience)
  • Neurolucida (MBF Bioscience)
