Research in our sleep labs focuses on functionality of the sleeping brain using a multimodal imaging approach.
This approach includes functional magnetic resonance imaging (fMRI), EEG, cerebrovascular physiology and cognitive techniques.
Sleep is critical for both health and cognition. Our lab is developing ways to manipulate sleep (called sleep engineering) in order to maximise its beneficial properties.
We're working on ways to enhance memory, disarm negative emotions, and combat cognitive decline through ageing. You can visit our dedicated Neuroscience and Psychology of Sleep (NaPS) lab page to find out more about our research and ongoing projects.
People
Our principal investigator, Professor Penny Lewis, has authored a number of academic publications, given a TEDx talk, written a Popular Science book on sleep and edited an anthology of sleep stories.

Facilities
Built for sleep studies and observations
We have five sleep bedrooms, three of which are intended for cognitive studies in healthy controls, and two of which are intended for clinical research.
The cognitive sleep lab is hotel-style with double beds, comfortable carpeted rooms, and good sound insulation. Each bedroom also functions as a cognitive testing lab so that participants can comfortably engage in tasks before sleep and immediately after waking.
The sleep labs are equipped with the latest in EEG technology from Brain Products, and our current set-up can measure up to 64 channels at one time. This includes:
- 3 x Brain Amp Mr Plus
- 1 x Brain Amp ExG MR
- 1 x Brain Amp ExG.
A control room is located next to the three bedrooms, which is arranged for EEG application and overnight researcher observation.
We promote a multi-modal approach to understanding research problems, therefore EEG can also be used simultaneously with other techniques such as fMRI. We also conduct clinical sleep studies at the Centre in our clinical research unit.
