From this tab you can browse and select from reporter lines and driver lines used in the creation of the Allen Mouse Brain Connectivity Atlas.
Search the Transgenic Mouse dataset by entering a gene symbol or mouse line name into the search box. Retinal Projectome data includes four experiments with vertical mount sections of the retina. You will be prompted with suggestions once you have started typing. Click "Search" or hit the Enter key.
You can also browse through the data using tabs on the search page that illustrate all of the Driver Lines and Reporter Lines used in this resource.
Each driver line is represented by its name, a representative image (which is magnified when clicked) and a description of expression. Clicking on the line name will return results from all characterization experiments for that particular line.
This tab lists all the characterized reporter lines with a description of their expression patterns.
Representative retinas were sectioned in the vertical plane for characterization of morphology and co-localization with markers for well defined retinal ganglion cell (RGC) types. Four markers were used:
Each experiment shows the GFP viral tracer infection in green, the marker in red and a DAPI stain in blue.
Clicking on Search will return a list of experiments based on your search criteria with information on the Experiment ID, Line Name, Driver, Reporter, Probes, Age, Sex, Treatments and Image Count. Click on the Experiment ID to be taken to the Experiment Detail Page
To compare multiple experiments, mark the checkboxes to the left of each row, then click the "Compare Selected Experiments" button. Note: the selection list may contain previously selected experiments from the "Projection" or "BDA/AAV" studies. Your choices are stored in a browser 'cookie' on your computer and will remain in effect until you click the "Clear Selections" button, or clear your Web browser cookie cache.
Clicking on the experiment summary link returns a summary of the experimental details (see screenshot).
The various sections of the experimental detail page are outlined 1-6 as follows:
The Zoom and Pan (ZAP) Image Viewer is a powerful tool to navigate and view the images in an experiment. The main part of the viewer is an interactive window where an image can be repositioned by dragging with a mouse. Use the scroll wheel, on-screen navigation buttons or the keyboard commands to zoom in or out.
Select other images in the experiment by clicking on a thumbnail image below the main viewer.
Drag the scale bar with your mouse to the desired location. Click the scale bar text with your mouse to toggle between horizontal and vertical.
Use the toolbar to take actions on the image that currently has focus. Toolbar controls include:
Select ISH, Nissl or Expression image type
Image adjust controls
Display all thumbnail images in a single contact sheet
Open the selected image in the High Resolution Image Viewer
Use the keyboard to navigate through the image series and synchronize the viewers on the page. Keyboard commands include:
Advance to the next image in the series
Go back to the previous image in the series
Advance to the last image in the series
Go back to the first image in the series
Sync all viewers on the page to the zoom level and location of the active viewer
Zoom in. Please note that some keyboards may require the [Shift] key be held down while pressing the [+] key
You can also use the arrow keys to pan the current image.
The expression mask image display highlights those cells that have the highest probability of gene expression using a heat map color scale (from low/blue to high/red).
The Expression Energy was calculated as follows: Within a given area A (voxel or structure), expression energy = (sum of intensity of expressing pixels in A) / (sum of all pixels in A)
