Laboratory description

The aim of the Budapest Laboratory of Sleep and Cognition is to examine human behavior with a special focus on sleep and its role in information processing. In our view, sleep provides an exciting “natural environment” to explore and unravel the neural activity of the brain as well as its more specific functions or dysfunctions. Our research topics extend from basic neurophysiological studies to more complex experiments focusing also on the behavioral level. Our aim is to understand sleep and sleep-related cognitive and affective processes in their entirety integrating multiple (physiological, cognitive and phenomenological) levels of analyses.


Technical Capabilities and areas of expertise

– PSG (with 32, 64 and 128 channel EEG)
– ECG (focusing on Heart Rate Variability)
– EDA (Skin conductance)
– Cognitive test batteries, psychometric tests.


Additional Descriptors, Keywords

Nightmare Disorder, REM sleep, Chronotype
