Tietomuisti sis\u00e4lt\u00e4\u00e4 yleist\u00e4 faktatietoa, kun taas tapahtumamuisti sis\u00e4lt\u00e4\u00e4 aikaan ja paikkaan sidoksissa olevia kokemuksia. Uni sen sijaan jaetaan perusuneen (engl. non rapid eye movement sleep eli NREM) sek\u00e4 vilkeuneen (engl. rapid eye movement sleep eli REM). Unessa esiintyy my\u00f6s erilaisia mikrorakenteita. Asiamuistiin luokiteltavissa olevan tiedon omaksumisessa ja konsolidaatiossa keskeisess\u00e4 asemassa ovat kaksi perusunen mikrorakennetta: unisukkulat ja hidasaallot. Yksi keskeinen perusunen mikrorakenne on my\u00f6s K-kompleksi. Sen merkityst\u00e4 asiamuistin toiminnassa ei kuitenkaan juurikaan ole tutkittu.

Long-term memory is generally divided into procedural and declarative memory. Procedural memory comprises skills and procedures, whereas declarative memory comprises semantic and episodic memories. Semantic memories comprise factual information and episodic memories comprise time and place specific memories. Sleep, for its part, is divided into non-rapid eye movement (NREM) sleep and rapid eye movement (REM) sleep. Within the NREM and REM sleep, there are different microstructures. Central to the encoding and consolidation of declarative memories is the functioning of two NREM sleep microstructures: spindles and slow oscillations. However, it remains almost completely unexamined whether another important NREM microstructure, K-complex, has a role in the functioning of declarative memory. In this study, we measured the participants\u2019 sleep via polysomnography (PSG) in three subsequent nights. Additionally, we measured their semantic memory via Rey Auditory Verbal Learning Test and episodic memory via a test named Logical Memory. The participants conducted the tests on the day after the second night\u2019s PSG recordings. Furthermore, the participants conducted delayed recalls on the day after the third night\u2019s PSG recordings. The results of our study showed that the K-complex quantity is not affected by the encoding of declarative information but rather, the K-complex quantity is an individual feature that affects the declarative memory. The higher the individual\u2019s baseline quantity of K-complexes, the better their semantic learning potential. Our results therefore added to the knowledge of the connections between sleep and declarative memory by showing that the activity of K-complexes is also relevant to the functioning of declarative memory. We speculate that the importance of K-complexes on the declarative memory functions might be explained by the intertwinement of K-complexes, slow oscillations, and spindles. In addition, our results indicated that semantic memory mainly benefits from NREM sleep, whereas episodic memory benefits from REM sleep. Thus, our study not only showed that the K-complex activity may have an important role in the functioning of semantic memory, but also that different sleep-dependent processes underlie the two declarative memory components.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2019-06-04T07:21:08Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2019-06-04T07:21:08Z (GMT).
