Hi Svenja, if you build surfaces we distribute probabilistic surface maps for the BA labels that are surprisingly accurate (see https://surfer.nmr.mgh.harvard.edu/ftp/articles/ba_maps2007.pdf) I think they also distribute a volumetric atlas, but the spatial probabilities are quite blurry. cheers, Bruce On Fri, 13 Mar 2009, Svenja Diekhoff wrote: > Hi there, > > I was wondering whether it is possible to get information about how many percent of a certain fMRI activation blob are located within a certain brain area using the Juelich Histological Atlas, e.g. 52 % BA4a, 30% BA4p, 18% BA6 or something like that. > > I would be very happy about any comments or ideas! > > Kind regards, > Svenja > > >
