Every experiment conducted in this study is shown by default on the Experiment Overview page. In the Allen Brain Observatory Visual Coding study, an Experiment is composed of a series of three one-hour long two-photon calcium imaging sessions on an awake mouse exposed to a series of visual stimuli. An experiment is the unique combination of one mouse, one imaging depth (e.g. 175 um from surface of cortex), and one visual area (e.g. “Anterolateral visual area” or “VISal”). More information on the experimental design and the visual stimuli can be found from the whitepapers located in the Documentation.

Targeted Functional Visual Areas


With the inaugural release, all of the columns (minus the two common mouse lines) are displayed by default. The "View Cells" and "Experiment" columns will take you to the #Cell List and the link takes the user to a page with information on each of the cells identified in the experiment (link to Cell Overview page). The ‘Experiment’ column shows a thumbnail image of the calcium imaging field of view for one of the imaging sessions in the experiment. #Experimental Detail Page, respectively. Each of the remaining columns display displays a visualization summarizing the population response of all the neurons in the calcium imaging field of view in response to one of the specific visual stimuli. The population thumbnails are shown below and can be explored in more detail from the #Experimental Detail Page.
