Automated Anatomical Labeling (AAL, or anatomical automatic labeling) is a software and a digital human brain atlas with a labeled volume. Labels are indicating macroscopic brain structures. As software AAL is available as an SPM plugin for the versions SPM99, SPM2, SPM5 and SPM8. The software is available from

http://www.gin.cnrs.fr/spip.php?article217

The brain region ontology of the Brede Database records the identifiers used in the AAL atlas:

For the Brede Wiki see the category Brain regions in AAL

The AAL cortical parcellation map are also used in the SRI24 human brain atlas under the name SRI24/TZO.


[edit] Code example

The following code uses functions from the Brede Toolbox to extract from an Analyze file each individual brain region to its own file:

V = brede_read_analyze('aal');
for n = 1:116
    brede_write_analyze(brede_vol_threshold(V, n, 'type', '='), 'filename', sprintf('aal-%d', n));
end

With Python reading the 'readme.txt' file in the AAL distribution:

names = ([line.split()[0] for line in open('readme.txt').readlines()[74:190]])
print('# [[' + "]]\n# [[".join(names) + ']]')
