An information-theoretic analysis on the limits of brain registration
Hiroki Yamamoto (Kyoto Univ.) NC2010-32
Abstract (in Japanese) (See Japanese page) 
(in English) Intersubject brain registration is widely used to describe the loci of brain activation or lesions, and to normalize functional data between individual brains. The present study evaluated three registration algorithms – linear volume-based, nonlinear volume-based, and surface-based methods – using probability and entropy maps. We found that the surface-based method gave the best results for probability (average probability: ~0.3) but lost its advantage for entropy (average entropy: ~ 1 bits). This suggests that the current technology is far from perfect and thus should be used with caution about the limits.
