Yet the processes which might account for these time-dependent variations remain obscure. Here we assess the contribution of homeostatic and circadian factors to the generation of NREM mentation across the diurnal cycle. Assuming that previously reported time-of-night mentation effects are primarily driven by a circadian activation cycle which approximates the core body temperature (CBT) rhythm, it was hypothesized that more content would be reported from daytime nap awakenings as compared to night awakenings. Afternoon Nap reports were compared to previously-collected nocturnal reports from Circadian Nadir and Late Morning time points. Contrary to our hypotheses, both amount of mentation reported and propensity to report any mentation at all were lower in Nap as compared to Late Morning reports. A purely circadian influence following the CBT cycle is inadequate to explain this pattern of mentation production. date: 2008 date_type: published id_scheme: ojs official_url: https://journals.ub.uni-heidelberg.de/index.php/IJoDR/article/view/77 ppn_swb: 1403009902 own_urn: urn:nbn:de:bsz:16-opus-94017 language: eng bibsort: WAMSLEYERIHOMEOSTATI2008 full_text_status: none publication: International Journal of Dream Research volume: 1 number: 2 pagerange: 27-33 citation: Wamsley, Erin ; Antrobus, John S.
