Novel Methods for the Visualization and Analysis of Functional Maps in Cortex

Flat Maps 29 3.8 Types of Flat Maps There are anatomical flat maps and functional flat maps. It is possible to overlay functional data from fMRI experiments onto anatomical data, as can be seen in Figure 15 later in this chapter. Anatomical flat maps are obtained by flattening the folded gray matter. Therefore, they are flattened representations of the cortical gray matter.
