Measuring and comparing brain cortical area and other areal quantities

Presentation at the NeuroMat workshop “Random Graphs in the Brain“, Institute of Mathematics and Statistics, University of São Paulo, 23-27 November 2015.

Measuring the surface area is important in that it appears to be closer to gene action than the cortical volume, which is influenced by cortical thickness and folding. The method allows investigation of the area at every point in the cortex, thus giving localising power otherwise unavailable with regions of interest, and giving a result that is interpretable on its own right.
