This is a version of the ICBM Average Brain – an average of 152 T1-weighted MRI scans, linearly transformed to Talairach space – that is specially adapted for use with the MNI Linear Registration Package (mni_autoreg).

Methods

In 2001, within the ICBM project (Mazziotta et al., 1995, 2001a,b), three sites (MNI, UCLA, UTHSCSA) each collected ~150 MRI volume images from a normative young adult population. These images were acquired at a higher resolution than the MNI305 data and exhibited improved contrast. To create MNI152, each individual in the MNI cohort was linearly registered to MNI305. This new template exhibits better contrast and better definition of the top of the brain and the bottom of the cerebellum due to the increased cover- age during acquisition.

Demographics

• Handedness was scored on a scale of 0-10.  Average(std dev) for 141 of the 152 subjects was 8.57(2.50) with a range of 1-10 and interquartile range 8-10.
• Age, measured in years:  25.02(4.90)y, range 18-44y, interquartile range 21-28y
• 86 males and 66 females
• Ethnic background: 129 caucasian, 15 asian and 1 mixed decent
