This atlas takes advantage of ultra-high resolution 7T MRI to provide unprecedented levels of detail on structures of the basal ganglia in-vivo. The ATAG atlas includes probability maps of the striatum, GPe, GPi, red nucleus, substantia nigra, subthalamic Nucleus(STh) and the PAG. The atlas has been created on 30 young (M:24.2), 14 middle-aged (M: 52.5), and 10 elderly (M: 69.6) participants.

Separately a STh atlas was created based on 13 young (M:24.38), 8 middle-aged (M:50.67), and 9 elderly participants (M:72.33).
