Famous brains

Talairach brain (single)
the brain dissected and photographed for the famous Talairach and Tournoux atlas.
The atlas has Brodmann’s areas labelled, albeit in a rather approximate way.
MNI 305 brain (average of 305 brains, all right handed, 239 M, 66 F, age 23.4 +/- 4.1)

ICBM152
the average of 152 normal MRI scans that have been matched to the MNI305 using a 9 parameter affine transform.
adopted this as their standard template; it is the standard template in SPM99 and later.

colin27 (single subject)
one of the MNI lab members, Colin Holmes, was scanned 27 times, and the scans were coregistered and averaged to create a very high detail MRI dataset of one brain. This average was also matched to the MNI305, to create the image known as “colin27”. colin27 is used in the MNI brainweb simulator. SPM96 used colin27 as its standard template. SPM96 and later contains a 2mm resolution copy of the same image, in the canonical directory of the SPM distribution. In SPM96 this is called T1 in later distributions it is called single_subj_T1. Note that the images in the SPM “templates” directories have all been presmoothed to 8mm for use with the normalization routines.

H.M. (Henry Gustav Molaison)
A famous patient with memory loss. His hippocampus was largely removed in a surgery. As a result he couldn’t commit new events to long term memory. The slices of his brain is now at UCSD.
