Experimental sleep fragmentation impairs attentional set-shifting in rats.
STUDY OBJECTIVE To evaluate the effect of experimental sleep fragmentation (sleep interruption; SI) on complex learning in an intradimensional-extradimensional (ID/ED) set-shifting task in rats. DESIGN A sleep fragmentation paradigm of intermittent forced locomotion was validated in adult rats by examining electrographic effects. Discrimination task performances were assessed in rats followin...
متن کاملSleep fragmentation, sleep deprivation, or both.
I applaud the efforts of Schwartz and Moxley to explore ways to achieve greater understanding of the role of arousals in producing daytime impairment.1 This area of research has great clinical relevance, but has been largely neglected in recent years. Schwartz and Moxley distinguish short arousals (3-15 secs) from long arousals (15-60 secs) and wake events (>60 secs). They found that long arous...
متن کاملExperimental sleep fragmentation impairs spatial reference but not working memory in Fischer/Brown Norway rats.
Sleep fragmentation is a common symptom in sleep disorders and other medical complaints resulting in excessive daytime sleepiness. The present study seeks to explore the effects of sleep fragmentation on learning and memory in a spatial reference memory task and a spatial working memory (WM) task. Fischer/Brown Norway rats lived in custom treadmills designed to induce locomotor activity every 2...
متن کاملSleep fragmentation in the arthritic rat.
We examined the diurnal sleep-wake patterns in the adjuvant arthritic rat. In contrast to control rats, arthritic rats lacked a normal diurnal variation in sleep and wakefulness. Thus, arthritic rats exhibited no differences in the mean number or duration of bouts of sleep and episodes of wakefulness between light and dark hours. Arthritic rats also had a marked increase in the fragmentation of...
متن کاملImproving the utility of interpreting sleep fragmentation.
275 R ecognition of the importance of EEG arousals in determining daytime function was facilitated by the development of the multiple sleep latency test (MSLT) as an objective measure of physiological sleepiness. Once the MSLT was incorporated into routine clinical practice, Roth et al 1 found that of all EEG-based sleep parameters, shifts to stage one sleep were the best predictors of sleepine...
