Identification of new methods for treating insomnia by studying brain activity during sleep and wakefulness

Célyne Bastien studies the psychological and physiological aspects of insomnia to understand its effects on people and to find ways of treating them. She is particularly interested in the mechanisms of sleep protection (which make it possible to remain asleep) and compares the objective quality (measured in the laboratory) and the subjective quality (reported by the individuals) of sleep in good sleepers and insomniacs.

Dr. Bastien studies the activity of the brain during sleep by electroencephalogram, which allows her to identify sleep characteristics of insomniacs that distinguishes it from the sleep of good sleepers. Neurophysiological and neuropsychological measures are also used to compare the objective and subjective quality of sleep and its perception. These measures allow for personalized interventions to help people adopt behaviors and attitudes that promote sleep.

Difference in level of alertness, dreams and mental function during wakefulness in insomniacs.

Dr. Bastien has conducted studies showing that the brains of insomniacs remain in a state of hypervigilance during sleep, and that these people respond differently to stimuli (sound or visual) during sleep, but also while awake.

Dr. Bastien's team also recently studied the dreams of insomniacs, and their studies showed that good sleepers had more positive dreams, associated with feelings of joy and happiness, while insomniacs reported more negative dreams. This last discovery suggests that dream management techniques may help promote sleep quality.

Dr. Bastien is also interested in the links between sleep characteristics and learning ability and mental function upon awakening, as well as the links between insomnia and other psychiatric or mood disorders, such as depression. .

Another interest of Pre Bastien is the link between aging and quality of sleep.
