这两种皮层的模版用法上有什么不同？

Submitted by foxet on Sun, 03/16/2014 - 05:07

一个是我在wfu_pickatlas的brodomann模版。。一个是HarvardOxford-Cortical的皮层模版，

前者线，后者片状。。。我想问这样用法上有什么差异阿？两者都算是皮层的模版吗？

Brodmann Atlas

In the early 20th century
German neurologist Dr.
Korbinian Brodmann defined 52 regions of the cerebral cortex of humans
and monkeys that
appeared to have different cellular morphology and organization. 



Harvard-Oxford cortical and subcortical structural atlases


Probabilistic atlases covering 48 cortical and 21 subcortical
structural areas, derived from structural data and segmentations kindly
provided by the Harvard Center for Morphometric Analysis.

The latter Harvard-Oxford could be considered as an instance of Brodmann Atlas.

Moreover, someone argued that the Julich Atlases of Eickhoff/Amunts/Zilles/et al. may be the best Brodmann atlases.  You could found more options in fsl.   http://fsl.fmrib.ox.ac.uk/fsl/fslwiki/Atlases

谢谢，我还想问，既然Harvard-Oxford could be considered as an instance of Brodmann Atlas

为什么两个模版harvard－oxford的模版呈一片的。，那不是除了皮层，又包括了白质了？

Harvard－oxford atlas was developed for subdividing the human cerebral cortex on magnetic resonance images into gyral based regions of interest (ROIs). It was used in surface-space-based analysis (or fiber tracking in DTI), compared with the grey matter and white matter in volume space.
