- non-REM sleep phasic events: K-complexes and spindles
Today, many people intentionally cut down on sleep in order to make more time in the day for work and social demands. In addition, many people experience sleep disorders that disrupt sleep onset, sleep maintenance, or sleep efficiency. In all of these cases, the sleeper is experiencing a type of partial sleep loss. You need not pull and “all-nighter” to feel the ill effects on the next day! It is important to understand the extent of neurophysiological impairment resulting from this degree of sleep loss and the corresponding effect on daytime performance. This has widespread implications for work and scholastic performance, driving safety, military operations, and quality of life.
In order to investigate this relationship between sleep and daytime functioning, I employ a host of measures, including behavioural, EEG and event-related potentials (ERPs), which complement one another in the investigation of brain function and human behaviour. ERPs may be used to investigate cognitive processes that are associated with changing levels of arousal, such as speed of processing and attention. Both EEG and ERPs may be recorded from multiple electrode sites across the scalp, providing a topographic picture or “map” of on-going brain activity.
This general approach allows for investigation of moment-to-moment changes in brain physiology and performance during varying levels of sleepiness. These methods allow me to investigate a number of fascinating questions. Current research projects in the laboratory focus on examining the impact of varying degrees of sleep loss on brain function and performance, and the impact on emotion regulation in particular.
