The organizational principles of 'de-differentiated' cortical maps
A common model of cortical aging assumes more de-differentiated cortical maps that link to worse everyday behavior. We showed using 7 Tesla MRI that older adults' S1 maps are not more de-differentiated then younger adults' maps when looking at standard markers of cortical de-differentiation such as activation amplitude or map size. Rather, they show specific local and global map changes, where smaller distances between D2 and D3 link to better everyday behavior of the hand.

RESEARCH
Preserved rubber hand illusion in advanced age
The rubber hand illusion is an often used paradigm to investigate multisensory body representations in health and disease. Here, we used the rubber hand paradigm to answer the question whether or not the visual-tactile integration of bodily signals and the associated feeling of bodily ownership changes with increasing age. We show that there is no difference in explicit and implicit markers of the rubber hand illusion between younger adults (aged 20-30 years) and older adults (aged > 65 years). This indicates preserved pathways for establishing a multisensory representation of the bodily self in advanced age.

CONCEPT
Changes in embodiment influence cognitive aging
Aging is associated with dramatic deficits in a number of cognitive functions. Our recent review paper outlines that a high number of age-related cognitive deficits arise from problems in embodiment. We propose a novel NFL-framework of bodily aging to conceptualize these changes. Key insight: Sensory and cognitive deficits on older age link to age-related changes in embodiment.
