Abstract

Prior research on resting state functional connectivity has indicated a link between motor learning and several brain regions. Using a 32-channel electroencephalogram, we examined the connection between resting state intervals and motor-memory network brain consolidation between older and younger adults. We aim to better understand functional connectivity during resting states in the default motor network in aging populations by comparing performance after periods of sleep and wake. We hypothesize that sleep may affect functional connectivity in the default mode network and networks related to procedural memory, which will be more effective in younger adults than older adults. In addition, we seek to gather results on baseline resting state activity between older and younger populations to understand the memory consolidation threshold between groups prior to sleep or wake periods. Though the study is ongoing, with the data of 18 healthy young adult sleepers and 9 healthy older adult sleepers, we analyzed the functional connectivity of the motor cortex and occipital regions following a series of motor-memory tasks and resting states. We found that sleep enhanced behavioral memory performance with lower beta and delta band frequency during resting states for younger adults. These conclusions remain consistent with previous experiments on memory consolidation and resting state activity.
