Back to an overivew of flat mapping and pictures of flat maps of the cerebellum created in the Euclidean and hyperbolic planes and on a sphere or to some hyperbolic maps of the Earth.

Here are some older pictures of flat maps of the human cerebellum. These are from early 1999. As our methods improve and become refined, the maps may change. These flat maps of the cerebellum used a different cut along the brainstem. It was a "zipper cut" that travelled along one side of the purple line shown in this image and back along the other side of it, pinning the "zipper" at two points along the brain stem boundary. This type of cut has now been abondoned and I now remove a "patch" corresponding to the brain stem and fourth ventricle.

In this picture, the cerebellum has been identified and various regions have been color coded for identification purposes.

These are some example of flat maps of the cerebellum which I have created using this older approach. Functional PET information was obtained from a target interception task and imposed on the maps using a hot metal color scale with white corresponding to the peak activation.
