Automatic auditory and somatosensory brain responses in relation to cognitive abilities and physical fitness in older adults

Abstract In normal ageing, structural and functional changes in the brain lead to an altered processing of sensory stimuli and to changes in cognitive functions. The link between changes in sensory processing and cognition is not well understood, but physical fitness is suggested to be beneficial fo...
