With the current launch of the Allen Cell Types Database, we include electrophysiological recordings from over 800 individual cells, a subset of which also include morphological reconstruction and #Neuronal Neuronal Models. There are several methods to search this database; 1) enable specific filter parameters by selecting from the "Filters" menu, 2) select a cell from the "#Cell Cell Location" map, 3) use the slider bars in the Parallel Coordinate Plot or 4) select from one of the curated Electrophysiological or Morphological searches.

...

To filter the neurons in your list of results, select from the mouse line, the cortical layer (1, 2/3, 4, 5, 6), and the Cell Reporter (Positive or Negative). By

, only a subset of these cells are listed; however, you can alter the subset of cells represented by clicking on the "More Options+" link and selecting from categories that include "Hemisphere", "Dendrite Type", "Apical Dendrite", "Morphology", and "Models".

The #Cell Cell Location viewer is integrated with the Parallel Coordinate Plot and the Cell Summaries list of experimental results, and enables

Filtering the cells (using the #Filters Filters parameters or the sliders in the Parallel Coordinate Plot) will result in a change in the number of cells visualized on this map.

...

Clicking on the image of the cell (when available) will open a new page containing the #Morphology Morphology data.

The electrophysiological data itself can be viewed from this page, or downloaded to be visualized on another platform or in a third party program. The Allen SDK provides a simple Python module to support downloading metadata and NWB files for cells in the Allen Cell Types Database. Please see the Data API Client documentation page to see an example.

Clicking on the electrophysiology thumbnail will open a new page containing the #Electrophysiology Electrophysiology Results data.

Projected views of the biocytin filled neuron were constructed by composing the darkest intensity pixel from each plane of the image stack into a single plane.

...

From the Projected top view, you can zoom into the picture from the on-screen navigation tools, the #Keyboard Keyboard Commands or using your scroll wheel. The two views of the neuron are synched so zooming in on one will also zoom the other. Clicking on "View image stack" will take you to an image viewer to view the individual images taken of this neuron.

...

Clicking "View Image Stack" while browsing the Morphology data will take you to our image viewer. The title bar includes the Mouse Line, the Specimen ID, the structure and the hemisphere. The "Configure" icon opens a menu that will allow you to vary the image contrast and download the individual images. The entire image stack can be navigated through using the on screen navigation tools, using the #Keyboard Keyboard Commands or by clicking on the Projected Side View.
