How can I access the natural images used in the Brain Observatory?


#1

Each of the experiments contains the images (or info necessary to reconstruct them).

This Jupyter notebook demonstrates how to use the allensdk Python package to get or reconstruct each image:

Note that these images are warped when displaying them on the monitor so that each image pixel is occupies the same angle of the visual field no matter whether it is in the center of the screen (which is close to the mouse’s eye) or the edge (which is far).

A demonstration of how this warping affects the images can be seen here:
