RecruitingDevice studyMultimodal Musical Stimulation for Healthy Neurocognitive AgingThis is a Stage I randomized, sham-controlled trial on the effects of multimodal musical stimulation on working memory in aging. Neurologically healthy older and younger adults will be tested on working memory and electroencephalography in the first randomized controlled trial of music as a form of brain stimulation, with multimodal musical stimulation and control stimulation conditions. Results will test the causal role of oscillatory mechanisms of the brain on cognition, and will lay the groundwork to the first musical, neurophysiologically targeted, brain-stimulation device for reversing cognitive decline in aging.
