SRI24 is a human brain atlas. It is described in:

and volume files is available from

SRI24 uses the AAL cortical parcellation map under the name SRI24/TZO as well as the LONI Probabilistic Brain Atlas under the name SRI24/LPBA40.[1]

SRI24 is distributed under CC-BY-SA license[2] and request citation of the The SRI24 multichannel atlas of normal adult human brain structure paper. (However, the LPBA40 atlas is distributed under a non-commercial license).


[edit] Content

[edit] Labels available from contains:

Nifti volume fil with size 240 x 240 x 155.
Tab-separated text file with label identifiers and brain region name
CC BY-SA 3.0 license

Generate table with Python for brain region ID and name from the text file:

import re
for line in open('sri24/LPBA40-labels.txt').readlines():
    rowelements = line.split()
    label = rowelements[0]
    name = re.sub('R ', 'Right ', re.sub('L ', 'Left ', re.sub('_', ' ', rowelements[1][1:-1]))).capitalize()
    print("|-\n| %s || [[%s]] " % (label, name))

Read and show labeled volume file:

from nipy import load_image
import matplotlib.pyplot as plt
lpba40 = load_image('lpba40.nii')
plt.imshow(lpba40[:, :, 80, 0])
