Intracranial temperature across 24-hour sleep-wake cycles in humans.


Landolt, H P; Moser, S; Wieser, H G; Borbely, A A; Dijk, D J (1995). Intracranial temperature across 24-hour sleep-wake cycles in humans. NeuroReport, 6(6):913-917.

Abstract

The 24 h time course of intracranial temperature, recorded subdurally at the parahippocampal gyrus in six patients (19 24 h periods), exhibited a prominent 24 h rhythm with its crest located at 20-21 h. The declining trend of intracranial temperature between lights off and sleep onset persisted in the first nonREM sleep episode (studied in two patients, seven sleep episodes). The correlation between EEG slow-wave activity (SWA) in nonREM sleep and the change in temperature explained < 25% of the variance. Although the change in temperature tended to be more positive in REM sleep episodes than in nonREM sleep episodes, no significant increase was observed in REM sleep. The data indicate that intracranial temperature exhibits a marked 24 h rhythm, the time course of which is only slightly affected by nonREM/REM sleep and EEG synchronization.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
