Célyne BastienIdentification of new methods for treating insomnia by studying brain activity during sleep and wakefulnessCélyne 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... |

Marc HébertPromising discoveries on the effects of light on the brain, and the use of light to improve the health of night workers and to help diagnose psychiatric illnesses.Marc Hébert is a specialist in the study of the biological clock, or chronobiology, and photobiology, which is the study of the effects of light on the brain. His research has shown that light has important effects on mood, and, specifically, that blue light affects the biological clock. These discoveries have led to the development of technologies that directly affect people's health, using light to reduce the... |

Chantal MéretteDevelopment and application of biostatistical analysis methods for experimental and observational data in neuroscienceProfessor Chantal Mérette is a specialist in the analysis of the complex data that is generated in neuroscience studies. Thanks to her expertise and that of her team of biostatisticians and epidemiologists (specialists in the factors influencing the health of populations), her research has made it possible to detect and validate biomarkers of risk of major neurodevelopmental diseases, including schizophrenia, recurrent major depression, and bipolar disorder.... |

Charles M. MorinDiscoveries on the mechanisms underlying insomnia leading to more effective treatment approaches.Professor Charles Morin's research is aimed at advancing knowledge to promote a better quality of life for people suffering from sleep disorders, and more specifically insomnia. His research has led to the development of tools that are used around the world, such as the Insomnia Severity Index, and the Sleep Beliefs and Attitudes Scale, two questionnaires that are used to assess behaviors, beliefs and attitudes of patients with insomnia. He is also the author of numerous insomnia... |

Igor TimofeevStudies of the mechanisms leading to the consolidation of memory during sleep. Sleep consists of several phases that form cycles that are repeated several times during the night. These phases are characterized by distinct electrical activity patterns. Certain phases, especially slow wave sleep, allow the consolidation of memory. The strengthening of connections between neurons, called synapses, underlie this consolidation, and thus, learning. Professor Igor Timofeev's research aims to understand how brain activity waves are generated, propagate and contribute to this important... |

Annie VallièresProfessor Annie Vallières studies the social, psychological and cultural aspects of sleep problems. This approach allows her to better understand these disorders in a variety of contexts, including night workers, and in different countries and cultures. Most night workers have difficulties sleeping. These problems have significant negative consequences: depression, illness, digestive problems, in addition to absence from work and a higher risk of accident. Many of these difficulties can be explained by the fact that these workers' schedules cause them to have... |
