Sleep Lab

CHBH Sleep Lab Lead:
Dr Bernhard Staresina

Our research aims to elucidate the role of sleep for cognition and behaviour. The sleep laboratory houses two sleeping suites and a central control room. For continuous sleep recordings, we use a 64-channel BrainAmp electroencephalography (EEG) system with customised EasyCap sleep caps. Each sleep suite is equipped with desktop computers for stimulus delivery and experimental testing. External speakers are used for targeted memory reactivation (TMR) studies and closed-loop stimulation is accomplished via the OpenVibe software package.

How can researchers access the equipment within this lab?
To gain access to the sleep laboratory there are procedures for training, ethics and project proposals. For the procedures please see the CHBH Operating Procedures and Local Rules.

What research data is produced and what can we understand from this?
The EEG system records ongoing brain activity from humans subjects whilst they perform cognitive tasks and whilst they sleep. The tasks we use include memory, motor skills and attention and language comprehension. This allows for characterising the brain dynamics – such as neuronal oscillations – associated with a given cognitive function. During sleep, EEG is used to monitor different sleep stages online and to investigate the role of slow oscillations and sleep spindles on behaviour. Researchers at the CHBH have strong expertise in investigating the role of neuronal oscillations.

How is this lab contributing to the CHBH values and principles?
The sleep laboratory is used for conducting fundamental research on cognition as well as to investigate brain dynamics associated with neurological and psychiatric disorders. The data from the sleep lab is complementary to data from other techniques housed within the CHBH. Therefore, we are combining EEG sleep research with other techniques such as brain stimulationfunctional magnetic resonance imaging (fMRI) and measures of structural connectivity. The research conducted in the sleep laboratory is done in the spirit of open science and we strive to make our approaches and data freely available.
