 # This figure is a flatten map of the cortical surface. A number of regions of

-# In this viewer, press "I" to inflate the brain, "F" to flatten the surface,
-# and "R" to reset the view (or use the ``surface/unfold`` cursor on the right
-# menu). This viewer should help you understand the correspondance between the
-# flatten and the folded cortical surface of the brain.
