During active exploration, the brain can enter different states. To investigate the principles by which the internal brain states affect the neocortical brain representation of haptic events, the fellow will use fixed sets of artificial spatiotemporal tactile afferent activation patterns and subsequently the haptic display across spontaneously or experimentally induced changes in brain states to explore the related decoding. Furthermore, the principles of sensory augmentation, and its dependence on brain state, will be explored.
