Seminar: Prof Giulio Tononi

December 11, 2018 @ 12:00 - 13:00

Sleep: A Window on ConsciousnessCentre for Neural Circuits and Behaviour at the University of Oxford

Tuesday 11 December, 12pm at the Oxford Martin School, Old Indian Institute, Oxford


The Cortex Club is delighted to co-host, together with the CNCB, Prof Giulio Tononi from the University of Wisconsin-Madison, who will be talking to us about his research on the role of sleep on consciousness. Please join us on December 11th at the Oxford Martin School, located in the Old Indian Institute at 34 Broad Street, Oxford.


For further information please contact Fiona Woods (fiona.woods – at – cncb.ox.ac.uk).




How does consciousness come about, and how can the brain create a world even when it is disconnected from the environment? Consciousness never fades when we are awake. However, when awakened from sleep, we sometimes recall dreams and sometimes recall no experiences. Traditionally, dreaming has been identified with rapid eye-movement (REM) sleep, characterized by wake-like, globally ‘activated’, high-frequency EEG activity. However, dreaming also occurs in non-REM (NREM) sleep, characterized by prominent low-frequency activity. Recent work using no-task, within-state paradigms has identified a ‘posterior hot zone’ where the EEG must be activated for subjects to experience dreams. Localized, content-specific activations occur depending on whether one dreams of faces, places, movement, and speech. These findings highlight the likely neural substrate of our own experiences and suggest some of the necessary and sufficient conditions for consciousness.
