Electrophysiology amplifiers and software for Sleep Lab

The Sleep Research Laboratory at Brock University is a 3-bedroom facility where we investigate sleep, performance and cognition in humans. The long-term goal of the program of research is to understand the functional role of sleep in waking performance. Dr. Cote built the lab in 2000 with state-of-the-art equipment to record brain activity from multiple scalp sites during sleep and waking states. Recording brain wave activity from 64 sites across the scalp provides a dynamic picture or map of changes in arousal and attention that vary across the day and night. Dr. Cote and her students have published extensively on diverse topics including the effects of sleep loss on brain function and performance, the role of sleep in memory consolidation, cognitive benefits of a nap, consciousness at sleep onset and throughout the night, and quantitative analysis of EEG during sleep and wakefulness as it relates to human performance. ******The equipment used to record sleep and brain activity during waking performance is no longer functional. Replacement of the recording amplifiers is crucial for continuation of the program of research and training of highly qualified personnel. Software updates will also improve the efficiency of research output by providing access to modern analysis routines. This equipment will be used for Dr. Cote's NSERC-funded research which investigates the role of sleep in waking information processing. The most recent research grant (funded 2019-2024) aims to investigate the role of REM and non-REM sleep in emotion processing in particular. We will use highly novel paradigms such as deep sleep enhancement with auditory stimulation. Students at all levels receive highly specialized training in electrophysiology in the context of both sleep and waking cognitive performance. As many Canadians do not get the sleep they need, this research may help people to improve performance (work, scholastic, sport) through optimizing sleep, and may also inform intervention strategies in individuals with sleep, emotion, or behavioural disorders. *****
