Improved decoding of human brain activity using advanced functional magnetic resonance imaging at ultra-high field strength
While brain reading sounds like science fiction, it can be made possible by advanced methods in magnetic resonance imaging using the newest ultra-strong MR scanners. In this project pictures, movies and even imagined thoughts shall be decoded from brain signals by zooming into the smallest cortical units. To achieve this, it is necessary to rapidly image the dynamic changes within the brain at the level of cortical columns and layers. One of our goals is to develop a highly accelerated acquisition and reconstruction scheme that will provide the possibility for a high spatio-temporal resolution.
Functional magnetic resonance imaging (fMRI) is an important tool for non-invasive investigations of the human brain’s functional networks. Employing methods like blood oxygenation level dependent (BOLD) imaging, the human brain function can be mapped repeatably with high sensitivity.
This project is in collaboration with Marcel van Gerven and Christian Beckmann (Donders Institute, Nijmegen, The Netherlands).
