ANAEWARE CLINICAL TRIALS BEGIN
The AnaeWARE study opens for recruitment at the Imperial College Healthcare NHS Trust (Hammersmith Hospital). Eligible adult patients scheduled for elective surgery are invited to participate. The study focuses on identifying how anaesthetics affect the body by investigating changes in the relationships between different signals that are routinely monitored during surgery, with the addition of electrical brain activity (EEG) collected via a commercially available system. Patient participation involves giving us permission to record and store these signals in an anonymous database, and to analyse these signals offline. We are hoping that the data collected during this clinical trial will allow us to further characterise the action of anaesthetics on the body as a whole and identify “signatures” of loss /recovery of awareness that could potentially allow us to even predict the onset of awareness in a patient.
For more details see the AnaeWARE project page.
IEEE INTERNATIONAL SYMPOSIUM ON CIRCUITS & SYSTEMS
, Dorian Haci, Adrien Rapeaux and Timothy Constandinou attend and present their work at the 2015 IEEE ISCAS Conference in Lisbon, Portugal from 24-27 May 2015. Paper(s) presented by the Next Generation Neural Interfaces Lab include:

This three year, £1.44M IDEAS Factory project, is funded by the Engineering and Physical Sciences Research Council (EPSRC). SenseBack is led by Newcastle University and involves experts from the universities of Leeds, Essex, Keele, Southampton and our team at Imperial College London.
