The twitcing eye : REM sleep and the emotional brain
Sleep and emotion have been linked since the discovery of rapid eye movement (REM) sleep sixty years ago. Sleep, in particular REM sleep and the dreams it harbors, seems to modulate mood, restoring stability to the weary mind. Scientists have struggled to understand this link through the biological …

A central medullary circuit regulating REM sleep and pontine waves
Rapid-eye-movement (REM) sleep is a distinct behavioral state best known for its association with vivid dreaming in humans, as well as its theorized role in memory formation and consolidation. REM sleep is composed of tonic features such as hippocampal theta oscillations and skeletal muscle …

Effects of REM Sleep Deprivation on Trigeminal Nerves: Increased Thermal Sensitivity
Sleep is essential for maintaining normal functioning of the nervous system. Importantly, while sleep deprivation increases the level of pain, the pain resulting from injury, trauma, or infection can cause one to become sleep deprived. In such a scenario, a vicious cycle is established and is …

Phenotyping Behavioral Disorders in REM Sleep: Study of Digital Biomarkers of Neurodegeneration
Neurodegenerative disorders remain a significant challenge in modern medicine, with early diagnosis and intervention being critical for improving patient outcomes. This thesis focuses on advancing the understanding and detection of REM Sleep Behavior Disorder (RBD), a recognized prodromal symptom …

Investigating state-dependent pontine cholinergic activity during REM sleep and P-waves in vivo
Rapid eye movement (REM) sleep is a behavioural state during which phasic deflections in pontine LFP, known as pontine waves (P-waves), occur most prominently. Cholinergic pedunculopontine and laterodorsal tegmental nucleus (PPT/LDT) neurons have been implicated in the generation mechanisms of both …

Neural Dynamics of Mental Imagery, Visual Perception, and Rapid Eye Movement Sleep
… 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 neural activity …

Inhibitory Control of Muscle Activity in Sleep
… thesis, I examined the inhibitory control of REM sleep motor activity using both a pharmacological rat model and a genetic mouse model. I characterized the role for GABA and glycine in mediating the REM-specific suppression of muscle activity as well as their involvement in regulating the …

The functional neurophysiological sequelae associated with high frequency dream recallers
… 'arousal-retrieval' model positing that intra-sleep wakefulness is required for dream traces to be encoded into long-term storage, essentially proposing increased DRF as a product of a better memory for dreams. Results from recent studies support this model by demonstrating longer periods of …

The narrative of dream reports
… of a functional physiologicaL process of REM sleep, or whether they are akin to waking thought. Theories of REM sleep as a period of information-processing are reviewed. This is Linked with work on the relationship between dreaming and creativity, and between memory and imagery. Because of …

Employing Intracranial EEG Data to Decipher Sleep Neural Dynamics
Over the course of a typical night, sleep is comprised of multiple different stages that involve changes in brainwave patterns. Intracranial EEG (iEEG) is an invasive brain recording technique used in hospital settings in epileptic patients to determine the focus of their seizure activity. The …

STUDIO DEL RUOLO DELLA PROTEINA PRIONICA NELLA REGOLAZIONE DEL SONNO MEDIANTE L'UTILIZZO DI MODELLI MURINI TRANSGENICI
… electroencephalographic alterations but recently sleep modification have been described. Moreover a role for PrP in sleep has been proposed on the basis of data collected in Knock-out mice. We generated a new mouse model of CJD (Tg(CJD)) that express the murine homologue of the D178N/V129 human …

The relationship between elevated night-time Glucocorticoid activity and dreaming: a perspective on sleep-dependent memory consolidation
… levels, both during wakefulness and during sleep. Corticosteroid exposure is associated with changes in endogenous glucocorticoid activity, sleep disruption, episodic memory impairment, and reduced hippocampal volume. This dissertation had two primary aims. The first was to explore the …

On the Relative Contribution of Stress and Rapid Eye Movement Sleep Deprivation to the Retention Deficit Following Rapid Eye Movement Sleep Deprivation.
… 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, and …
