Ultra-High 7T MRI of Structural Age-Related Changes of the Subthalamic Nucleus

M. C. Keuken, P.-L. Bazin, A. Schafer, J. Neumann, R. Turner, B. U. Forstmann
2013 Journal of Neuroscience  
In the present study, ultra-high field 7 tesla (T) magnetic resonance imaging (MRI) in humans was used to visualize and segment the STh in young, middle-aged, and elderly participants.  ...  In sum, the results of the present study suggest that age has to be taken into account in atlases for the optimal localization of the STh in healthy and diseased brains.  ...  Due to its small size and close proximity to structures such as the substantia nigra and the red nucleus, it has been a challenge to localize and visualize the STh (Mai and Paxinos, 2008 ).  ...
