On the Relative Contribution of Stress and Rapid Eye Movement Sleep Deprivation to the Retention Deficit Following Rapid Eye Movement Sleep Deprivation.
The question of what role, if any, rapid eye movement (REM) sleep plays in memory consolidation has yet to be answered. Those studies which find evidence for a functional role of REM in consolidation do so by comparing REM deprived (REMD) animals, which are subjected to cold, wetness, isolation, …

Neural Dynamics of Mental Imagery, Visual Perception, and Rapid Eye Movement Sleep
… to better understand the functional role of rapid eye movement (REM) sleep, we sought to gain a deeper understanding of the differences between neural activity during REM sleep and during the awake state. We set out to investigate the temporal directionality of communication and coupling in …

Central autonomic control in spontaneously hypertensive rats: a study on phasic phenomena during rapid-eye-movement sleep
… wide changes in the different states of sleepwake cycle. In particular, the relationship between spontaneous fluctuations in heart period and arterial pressure clearly shows differences between the two sleep states. In non rapid-eye-movement sleep, heart rhythm is under prevalent …

An Examination of Two Possible Delineations of the REMS-Consolidation Hypothesis.
Research done in the 1950's demonstrated that sleep was not a homogeneous state, in fact, that it consisted of periodically recur- ring stages (Aserinsky and Kleitman, 1953). One of these stages is readily identifiable due to concurrent physiological changes: elevated temperature, increased …

Interactions between anterior thalamus and hippocampus during different behavioral states in the rat by Héctor Penagos.
… during periods of awake immobility, slow wave sleep (SWS) and rapid eye movement sleep (REM). Despite its close functional and anatomical association with the hippocampus, whether or how activity in the anterior thalamus is related to activity in the hippocampus during behavioral states …

An Investigation of Sleep Architecture and Consequent Cognitive Changes in Olanzapine Treated Patients with Depression
… the effect of olanzapine augmentation therapy on sleep architecture, specifically slow wave sleep (SWS), in the treatment of depression. Secondarily, to determine the effect of olanzapine augmentation therapy on illness severity and cognitive function. Finally, to examine the correlation between …

Group II Metabolic Glutamate Receptors in the Basal Amygdala Regulate Sleep and Fear-Induced Alterations in Sleep
… and anxiety as well as in the regulation of sleep and arousal. Our lab has found that the central nucleus of the amygdala (CNA) is involved in the emotional modulation of sleep. The basal amygdala (BA), which has direct connections with the CNA, is involved in conditioned fear and fear …

MCI IN RBD as a Distinct Clinical Entity: Comparative Evaluation of Diagnostic Frameworks and the cognitive domain as predictive factors of phenotypic conversion
Rapid Eye Movement Sleep Behavior Disorder (RBD) is a parasomnia characterized by loss of muscle atonia during REM sleep and the occurrence of dream-enacting behaviors, often associated with vivid and sometimes violent dreams. Increasing evidence supports that RBD represents an early clinical …

Investigation and Modelling of Fetal Sheep Maturation
… third-trimester with well-defined SWS (slow wave sleep) and REM (rapid eye movement) sleep states. For the late third-trimester, the results of power, correlation time, and SVD (singular value decomposition) entropy analysis demonstrate that the sleep state change is a cortical phase …
