In this piece we discuss all things EEG with Chris Connor, an anesthesiologist and researcher from Boston, USA, and Jamie Sleigh, an anesthesiologist and researcher from Hamilton, New Zealand. We start by discussing the engineering behind the BIS algorithm, then move to interpreting the raw EEG, the spectrogram and burst suppression. Finally we discuss the ‘titration paradox’ and how it might influence research and AI.

Presented by Andy Cumpstey and Kate Leslie on location at the Annual Scientific Meeting of the Australian and New Zealand College of Anaesthetists and Faculty of Pain Medicine in Cairns, Australia, with their guests, Dr Chris Connor, Assistant Professor and Vice Chair ad interim for Research, Brigham and Women’s Hospital, Boston, USA, and Professor Jamie Sleigh, Professor of Anaesthesiology and Intensive Care, Waikato Clinical School, University of Auckland, New Zealand.
