How Old is Your Brain: The Power of Neuroimaging to Advance Science and Health Practice

When we see the face of a person, we are pretty good at estimating their age. In other words, our brain is trained to judge the proportions of the different parts of the face, the increasing wrinkles, the decreasing elasticity, etc. This age estimation can also be achieved via computer algorithms, such as machine learning principles. Age estimation for faces seems natural and intuitive, but automated algorithms can also be used to estimate the age of brains. How is that possible? In this talk, I will demonstrate the underlying concept of this so-called BrainAGE approach, including methodological details. In addition, I will demonstrate various applications, ranging from creating a frame of reference for neurodevelopmental trajectories early in life, to the identification of protective and risk factors later in life. Last but not least, I will show how the BrainAGE approach can be used to predict an individual's risk of developing Alzheimer's disease, all based on a single structural brain scan.

Dr. Christian Gaser is an Associate Professor of Computational Neuroscience / Neuroimaging and the head of the Structural Brain Mapping Group at the University of Jena (Germany). His research program is directed toward the development of advanced computational tools for the analysis of structural brain data. Dr. Gaser is heavily involved in the advancement of algorithms and tools for processing voxel- and surface-based imaging data, which encompasses segmentation, surface reconstruction, correction of topology artifacts and conformal mapping. Among his many noteworthy achievements is the development of a framework to automatically and reliably provide brain age estimates.

Refreshments will follow the lecture at the Level 2 Reception Space
