These microstructures of sleep are thought participate in memory processing. Sleep\nspindles have previously been associated to declarative learning and memory and K-complexes\nhave been associated for example to sleep-based stimuli recognition in evoked response\nstudies. In addition, sleep spindles have previously been linked to initial learning potential.\nHowever, the role of these microstructures in audiovisual declarative learning remains\nunknown. In the current study, sleep was measured with polysomnography on three\nconsecutive nights and an audiovisual learning task was completed before and after nocturnal\nsleep (n=12). Here we show that sleep spindles and K-complexes in slow-wave sleep are\nassociated with learning potential and memory consolidation in an audiovisual learning task.\nInterestingly, both microstructures seemed to be more beneficial in slow-wave sleep than in\nlight NREM sleep in which the majority of these microstructures are observed. This suggests\nthat slow oscillations, sleep spindles and K-complexes together during slow-wave sleep could\nunderlie sleep-based consolidation and learning potential. The results of the current study\nhighlight the importance of slow-wave sleep for acquiring and strengthening new memories.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2020-04-02T06:09:46Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-04-02T06:09:46Z (GMT).
